Toggle1. Introduction
Understanding the differences between electrical raceways and conduits is essential when planning electrical systems for a construction project. Each system has its advantages depending on factors like the type of building, environmental conditions, and specific electrical needs.
By understanding these differences and considering factors like safety, compliance, cost, installation ease, and the specific demands of your project, you can make a more informed decision on which system will best protect and organize your electrical wiring.
In the following post, we will dive deeper into the details of raceways and conduits, exploring their types, benefits, and specific applications to help you choose the right solution for your electrical system.
2. What is an Electrical Raceway?
2.1 Definition and Basic Function
An electrical cable raceway is a system that serves as a pathway for electrical cables, providing a structure to route and organize multiple wires. They differ from conduits because they are usually open and not completely enclosed around the cables. Raceways can be mounted on surfaces, or sometimes underneath floors, to manage cable runs efficiently. They help keep cables neatly organized while offering protection from dust, debris, and physical damage.
2.2 Key Functions of Electrical Cable Raceways:
Cable Organization: Cable raceways allow multiple cables to be routed together in an orderly manner, making it easier to maintain and modify wiring configurations when needed.
Physical Protection: While not fully enclosed, raceways still provide a degree of protection against environmental factors like dust, dirt, and light impacts, depending on the design.
Safety and Compliance: By keeping cables from tangling or being exposed to physical damage, raceways help prevent potential electrical hazards, ensuring compliance with safety standards.
Easy Modification: Because raceways are typically open or partially enclosed, they allow for easy access to the cables, making it easier to modify or add new wiring without needing to dismantle large sections.
2.3 How Electrical Raceways Work?
Cable raceways work by providing a track or channel along which cables can be routed and organized. The cables typically rest inside or along the raceway, often secured by brackets or clips.
Installation: Cable raceways are often installed on the surface of walls, ceilings, or along floors. They may be mounted with clips, screws, or adhesive, depending on the type and design of the raceway.
Routing Cables: Once installed, the cables are arranged within the raceway, following the path designated by the raceway system. They may be secured using clips or other fasteners to prevent movement or tangling.
Accessibility: Since raceways are typically open or only partially enclosed, cables can be accessed easily for repairs, upgrades, or future modifications. Raceways that mount to the surface allow for easy access without disassembling or removing large parts of the installation.
Protection from Hazards: While not completely enclosed like a conduit, a raceway still provides some protection from dust, dirt, moisture, and light impact. It helps to prevent cables from being exposed to environmental hazards, reducing the risk of wear and tear over time.
2.4 Types of Electrical Raceways
Here are some common types of non-enclosed electrical raceways used for cable management:
Cable Trays:
Description: Cable trays are open channels or trays used to route large groups of cables. These trays are often mounted along ceilings or walls and allow cables to be laid out in a neat and organized manner.
Common Types: Ladder, ventilated, or solid-bottom trays.
Applications: Frequently used in industrial and commercial settings, such as factories, power plants, or data centers, where large volumes of cables need to be managed over long distances.
Surface-Mounted Raceway (Wiremold):
Description: Surface-mounted raceways are typically plastic or metal channels that run along walls or ceilings to route electrical wires. They are commonly used for low-voltage wiring, such as data cables or phone lines.
Applications: Used in residential or commercial spaces where cables need to be organized but are not embedded within walls. Often seen in home offices or entertainment systems.
Raceway Ducts:
Description: These are narrow, open ducts often used to house multiple cables along walls or ceilings. Unlike traditional conduit, raceway ducts don’t fully encase the cables, providing quick access for changes or additions.
Applications: Commonly used for low-voltage applications like telecommunications or audio/visual cables in commercial environments.
Open Cable Ladder Trays:
Description: Ladder trays are open design systems with horizontal rungs that support cables, similar to a ladder. These trays allow easy routing of cables while providing ample space for airflow to prevent heat buildup.
Applications: Typically used in data centers or industrial facilities where extensive cabling needs to be organized over large areas.
Cable Busways:
Description: Cable busways are modular, open raceway systems used for power distribution, consisting of aluminum or copper busbars housed in an open track.
Applications: These are commonly used for high-voltage and high-current applications in industrial or power generation settings.
2.5 Why Use an Electrical Raceway?
Electrical raceways are used for several important reasons, particularly for organizing, protecting, and simplifying cable management systems:
Simplified Cable Management: Raceways help reduce cable clutter by grouping wires together in an organized manner. This makes it easier to manage multiple cables and ensures that systems remain clean and orderly.
Protection from Environmental Factors: Raceways provide a basic level of protection from dust, moisture, physical impact, and accidental abrasion, reducing the risk of damage to cables and prolonging their lifespan.
Safety and Compliance: Properly managing cables with raceways ensures compliance with safety regulations, reducing the risk of electrical hazards like fires or electrical shorts.
Accessibility: Since raceways are often open or partially enclosed, they provide easy access for cable modifications or replacements. This is particularly useful in spaces that need frequent changes or maintenance.
Aesthetic Considerations: Raceways help to maintain a clean and aesthetically pleasing environment by keeping cables hidden from view, especially in residential or commercial spaces.
2.6 Applications of Electrical Raceway
Electrical raceways are commonly used in a variety of settings for both low-voltage and high-voltage systems. Some of the typical applications include:
Residential and Commercial Buildings: Raceways are often used in homes and offices to organize and protect low-voltage wiring like data and phone cables, ensuring they’re neatly hidden or organized along walls.
Industrial and Manufacturing Facilities: In industrial environments, raceways are used to route heavy-duty electrical cables through production areas, ensuring that cables are protected from machinery and heavy traffic.
Data Centers: Raceways like cable trays are critical in data centers for organizing the large numbers of data cables that run between servers, routers, and other equipment.
Power Plants: For large-scale operations such as power plants, cable raceways provide a safe and organized way to route extensive electrical cables across expansive facilities.
Retail and Hospitality: In retail and hotel spaces, raceways help organize and protect the wiring for lighting, point-of-sale systems, and security systems, ensuring cables are kept neat and accessible for future maintenance.
3. What is an Electrical Conduit?
3.1 Definition and Basic Function
An electrical conduit is a type of pipe specifically designed to protect electrical cables and wires from external damage while providing a secure and organized route for wiring. The primary function of a conduit is to house electrical cables, safeguarding them against physical harm, moisture, corrosion, and other environmental factors that could potentially disrupt the safe operation of the electrical system. Conduits also ensure that electrical wiring remains properly organized and easily accessible for maintenance, upgrades, or future repairs.
3.2 How Electrical Conduit Works
Electrical conduits function as protective channels for electrical wiring. These conduits can be rigid or flexible, depending on the installation needs and the environmental conditions of the area. The conduit provides a secure and stable housing that keeps electrical cables from being damaged by impact, environmental elements (like water and chemicals), or accidental interference.
In typical applications, wiring is threaded through the conduit either during or after construction. The conduit itself may run along a building’s walls, floors, or ceilings, or it can be buried underground to provide long-term protection against the elements. Conduits also facilitate the ease of wire installation and maintenance, as they can be easily accessed, and the cables can be replaced or upgraded without having to remove significant portions of the building structure.
3.3 Why Use Electrical Conduit?
There are several important reasons why conduits are used in electrical installations:
Protection Against Physical Damage: Electrical conduits offer strong protection to electrical cables from external physical damage. Whether the cables are running along a busy street or in a high-traffic commercial area, conduits prevent them from being crushed, pierced, or cut. Without a protective conduit, cables are vulnerable to damage from equipment, tools, or even accidental impact. For example, an exposed wire running through a factory floor could easily be damaged by machinery, leading to potential electrical hazards. Conduits eliminate this risk by providing a solid barrier around the wiring.
Prevention of Environmental Damage: In harsh environments—such as outdoor areas exposed to moisture, extreme temperatures, or corrosive substances—electrical wiring is at risk of being compromised. Conduits provide a protective barrier that shields cables from elements like rain, snow, chemicals, or humidity, ensuring the integrity and longevity of the electrical system. For example, PVC conduits are commonly used in underground applications where moisture resistance is crucial, while steel conduits may be used in industrial areas with high temperatures or corrosive chemicals.
Organization of Electrical Wiring: One of the core functions of electrical conduits is to organize electrical wiring. Instead of having wires run loosely or exposed in a disorderly fashion, conduits help keep them contained and properly arranged. This not only helps to avoid clutter but also simplifies the process of installation, maintenance, and upgrades. In large buildings with numerous wires, such as office buildings, schools, or factories, having a conduit system helps reduce confusion, prevents wiring tangling, and allows technicians to work more efficiently.
Improved Safety: Electrical safety is paramount, and one of the key reasons for using conduits is to prevent electrical accidents. By encasing wiring in a conduit, you reduce the risk of accidental contact with live wires, thus minimizing the potential for electrical shock, fires, or short circuits. In areas where people may come into contact with the wiring—like commercial or residential spaces—conduits provide an extra layer of insulation, shielding the wiring from being exposed or damaged.
Code Compliance: Electrical codes and regulations, such as the National Electrical Code (NEC) in the United States, often mandate the use of conduits in specific environments or for particular types of electrical installations. For instance, underground wiring is often required to be run inside conduit to prevent moisture damage. Additionally, certain areas with increased fire risk (such as commercial kitchens or industrial facilities) may require conduits for added protection. Compliance with these codes ensures that the electrical system is safe, meets all necessary standards, and avoids penalties or complications in case of inspections.
Ease of Maintenance and Upgrades: One of the benefits of conduit systems is the ease with which electrical wiring can be maintained or upgraded. Wiring within a conduit is generally easier to access than in a traditional installation where wires are hidden behind walls or ceilings. If you need to replace old wiring or add new cables, the conduit system allows you to do so with minimal disruption. In contrast, rewiring a system without conduits often requires tearing out walls or ceilings, making the process more costly and time-consuming.
3.4 Types of Electrical Conduit Materials
Electrical conduits can be made from various materials, with each offering specific advantages depending on the environment, application, and installation requirements.
3.4.1 Metallic Conduits
Galvanized Rigid Steel (GRS): This is a heavy-duty conduit often used in industrial applications where protection from physical damage is critical. It is strong and durable, offering excellent protection against mechanical impact and environmental conditions.
Electrical Metallic Tubing (EMT): EMT is a lightweight, thin-walled conduit made of galvanized steel. It is often used in commercial and residential installations where protection from physical damage is still important but where flexibility and ease of installation are also priorities.
Aluminum Conduit: This is a lighter alternative to steel conduit, offering corrosion resistance while still providing strong physical protection. Aluminum conduits are often used in outdoor environments or where weight is a concern.
Flexible Metal Conduit (FMC): This type of conduit is made from a spiral-wound metal strip, offering flexibility for applications where the conduit needs to bend around obstacles or where rigid conduit might be difficult to install. It is often used in settings that require movement or frequent changes, such as machinery or power equipment.
3.4.2 Non-Metallic Conduits:
PVC Conduit: Made from polyvinyl chloride, PVC is one of the most common types of non-metallic conduit. It is highly resistant to corrosion, moisture, and environmental damage, making it ideal for use in underground, wet, or corrosive environments. PVC conduit is lightweight, easy to install, and relatively inexpensive, making it a popular choice for residential and commercial installations.
Typically have two types, rigid plain conduit and flexible conduit, flexible conduit so called corrugated conduit or ENT,we make a brief introduction alone in the following.
Non-Metallic Flexible Conduit /Electrical Non-Metallic Tubing(ENT):
Made from a flexible plastic material, this conduit is often used in environments where flexibility is required but a non-metallic option is preferred. It is lightweight, easy to install, and resistant to moisture and chemicals.
Fiberglass Conduit: Fiberglass is a corrosion-resistant material that provides excellent protection in harsh environments where metal conduits might not be suitable. Fiberglass conduits are typically used in areas exposed to chemicals, moisture, or extreme temperatures, where other conduit types might deteriorate over time.
HDPE Conduit: High-Density Polyethylene (HDPE) conduit is a type of non-metallic conduit made from a durable thermoplastic material. It is known for its flexibility, resistance to corrosion, and ability to withstand a variety of environmental conditions. HDPE conduits are widely used for electrical, telecommunications, and utility installations, particularly in underground and outdoor applications.
3.5 Applications of Electrical Conduit
Electrical conduits are used in a wide range of applications across different sectors, from residential buildings to large industrial facilities. Some of the most common applications include:
Residential Wiring: Conduits are often used in residential homes to route wiring for outlets, switches, and light fixtures. PVC conduit is commonly used in homes for wiring that runs outside or underground.
Commercial Buildings: In commercial spaces like offices, shopping centers, and hospitals, conduits are used to ensure safe, organized wiring. EMT or GRS conduits are frequently used in commercial settings for exposed wiring.
Industrial Facilities: In factories or plants, electrical conduits are essential for protecting wiring from mechanical damage, chemicals, or extreme environmental conditions. Heavy-duty conduits such as GRS or fiberglass are often used in these settings.
Underground Installations: Conduits provide crucial protection for wiring installed underground, where they are susceptible to moisture and physical damage. PVC conduit is the most common choice for underground applications.
4. Key Differences Between Electrical Raceway and Electrical Conduit
4.1 Shape and Design
Electrical Raceway:
Shape: Raceways are typically rectangular or trough-like in shape, although their form can vary depending on the type. The general design features open or partially enclosed systems, allowing for multiple cables to be routed in an organized manner.
Flat or Low Profile: Many raceways are flat, surface-mounted systems (such as Wiremold), designed to sit flush against walls, ceilings, or floors. These raceways have a low-profile rectangular shape, making them easy to install along existing structures.
Modular and Expandable: Many raceways, such as wireways, are modular, which means they can be expanded and adjusted in length or layout to fit the specific needs of an installation. Their design allows for easy additions or modifications to the wiring as systems grow or change.
Electrical Conduit:
Shape: Conduits are cylindrical in shape and are typically either rigid or flexible tubes. The cylindrical shape provides structural strength and durability, especially for protecting the electrical wires from external damage.
Rigid Conduits: These are solid tubes, typically made of PVC, steel, or aluminum, and come in a round or circular cross-section. This cylindrical design makes them resistant to compression and ideal for protecting cables in harsh environments.
Flexible Conduits: These are typically corrugated, allowing them to bend easily to fit around corners or into tight spaces. Flexible metal conduit (FMC) and liquid-tight flexible conduit (LFMC) are common types, often used for applications requiring bending or flexible routing.
Feature | Electrical Raceway | Electrical Conduit |
Shape | Rectangular, flat, or trough-like; can be modular | Cylindrical (rigid or flexible tubes) |
Design
Type |
Open or partially enclosed (e.g., cable trays, wireways) | Fully enclosed (solid or corrugated tubes) |
Installation Profile | Flat, low-profile for surface-mounted or recessed installations | Round for rigid or flexible piping |
Capacity | Large open spaces, designed for multiple cables | Limited internal capacity, tailored for individual or smaller cable bundles |
Protection | Provides limited protection; mainly for organization and accessibility | Superior protection from external damage, moisture, and environmental factors |
Flexibility | Easily expandable and adaptable to new configurations | Flexible or rigid, but less adaptable after installation |
4.2 Installation Methods and Adaptability
Raceways
Surface-Mounted: Many raceways, especially surface-mounted varieties, are designed to be fixed to walls, ceilings, or floors using screws or adhesive. These types are often rectangular or trough-shaped to allow cables to sit securely.
Recessed: Raceways can also be recessed into walls for a more aesthetic look. The rectangular or flat design fits neatly into drywalls, providing a hidden yet accessible path for cables.
Flexible Layouts: With modular designs, raceways can accommodate straight, curved, or complex paths and can easily be modified in the future without disrupting the system.
Conduits
Fixed Pathways: Conduits, especially rigid conduits (PVC, steel), are typically installed along a fixed route that requires cutting, threading, and securing using clamps or joints.
Bending and Curving: Rigid conduit can be bent using specialized tools (e.g., conduit benders), but the process is more labor-intensive than with flexible raceways.
Limited Modification: Once installed, it’s harder to alter the conduit path without making significant changes or cuts. Flexible conduits, however, can be routed into tight or irregular spaces.
4.3 Physical Protection: Enclosed vs. Open Designs
Raceways
Partially Enclosed: Raceways like cable trays and surface-mounted raceways are only partially enclosed, with open-bottom or removable covers. These designs allow for easier cable access and modification but provide limited protection from external impacts or environmental factors.
Access for Maintenance: Since raceways often have removable covers, they are ideal for maintenance, as technicians can quickly access the cables without disrupting the system.
Conduits
Fully Enclosed: Conduits are designed as fully enclosed systems, with a sealed cylindrical shape that protects wires from physical damage, moisture, and other environmental hazards.
Durable Protection: The cylindrical shape provides superior physical protection, especially in areas exposed to extreme conditions (e.g., industrial settings or outdoor environments).
4.4 Size and Capacity
Raceways
Larger Capacity for Multiple Cables: Raceways can handle a higher number of cables due to their wider, open designs. For instance, cable trays or wireways can support multiple cables simultaneously, making them ideal for large-scale installations.
More Space for Ventilation: Open raceways like cable trays allow for better ventilation and cooling of cables, reducing the risk of overheating when carrying high-voltage or high-ampacity wiring.
Conduits
Tighter Capacity: Conduits, being cylindrical, generally have less space for wire management and are more focused on protecting individual conductors.
Amperage Capacity Limits: The interior cross-sectional area of conduits is limited, so proper sizing is essential to prevent overheating or excessive wear on cables. The NEC limits conduit fill to 40% of the internal area to maintain safe operation.
5. Key Considerations for Choosing Between Raceway and Conduit
When designing an electrical system, choosing between raceway and conduit is a crucial decision that impacts both the safety and efficiency of the installation. Both systems are used to protect and route electrical wiring, but they each have distinct features, benefits, and limitations.
5.1 Type of Installation (Surface vs. Embedded)
One of the primary considerations when choosing between raceway and conduit is whether the installation will be surface-mounted or embedded within a structure. This choice significantly affects both the system’s installation process and its long-term functionality.
Raceways: Typically, raceways are used for surface-mounted installations where cables and wires are exposed or organized in a visible manner. Surface raceways, like Wiremold, are ideal for areas where aesthetics or future accessibility is a priority. They are easy to install, modify, and expand, making them a good option for retrofits or low-voltage systems (e.g., data cabling, telecommunication lines).
Example: In office buildings, surface-mounted raceways are often used to route low-voltage data cables along walls, keeping them organized and easy to access for upgrades or maintenance.
Conduit: Conduits are often used in embedded or in-wall installations, especially when the cables need to be protected from physical damage. Rigid conduits (e.g., RMC or EMT) are ideal for applications where the wiring needs to be safely protected from external forces or environmental conditions.
Example: Electrical conduits are typically used for heavy-duty wiring in industrial applications, where wires are embedded in walls or underground to prevent damage and ensure compliance with safety codes.
5.2 Safety and Compliance with Standards
Safety is a critical consideration when choosing between raceway and conduit. Both systems serve to protect the electrical wires inside, but they provide different levels of protection based on the materials used and their installation environment. It’s also important to ensure compliance with relevant building codes and safety standards.
Raceways: Raceways offer varying levels of protection depending on the type. For example, cable trays provide a high level of physical protection for multiple cables but do not fully enclose them, which can expose the cables to dust, moisture, and physical damage. However, raceways like wireways or busways are fully enclosed and provide enhanced protection.
Regulations: When using raceways, it is important to check the National Electrical Code (NEC) and local regulations to ensure that the wiring system meets safety standards, especially regarding filling capacities and heat dissipation.
Conduit: Conduits, particularly metallic and rigid varieties, offer superior protection from physical damage, chemical exposure, and environmental hazards. PVC conduit, while less durable than metallic conduit, is still widely used for applications requiring resistance to corrosion and moisture protection.
Safety Compliance: Conduit systems, especially for underground or outdoor installations, must comply with NEC regulations, including proper grounding and bonding, to reduce the risk of electrical shock or fire hazards.
5.3 Environmental Conditions (Temperature, Moisture, and Exposure)
The environmental conditions where the wiring system will be installed play a significant role in determining whether a raceway or conduit is the best choice. Factors like temperature, moisture, and chemical exposure will dictate which material and system design is more suitable.
Raceways: Raceways are more commonly used in dry and indoor environments, where minimal exposure to harsh conditions is expected. For instance, surface-mounted raceways work well in office buildings, residential areas, or areas with low risk of moisture or physical damage. However, in industrial or outdoor environments, raceways may not offer sufficient protection against elements like rain, dust, or extreme temperatures.
Conduit: Conduits are specifically designed for more rugged environments. For example, PVC conduit can be used outdoors or underground, while metallic conduit can handle extreme temperatures, abrasion, or chemical exposure in industrial settings.
Example: In outdoor installations, PVC or HDPE conduit is preferred for applications where moisture resistance and durability are crucial, such as underground wiring or installations in wet environments.
5.4 Installation Complexity and Cost
The installation process and associated costs can be significant factors when choosing between raceways and conduits. These factors can depend on the system type, ease of installation, and the overall project budget.
Raceways: Raceways, especially surface-mounted types, tend to be easier and faster to install than conduits. For instance, wiremold systems require minimal cutting and are often used for retrofit installations where cables are routed along existing walls. Raceways are typically less expensive and easier to work with, making them suitable for low-budget projects or areas where future modifications are expected.
Cost: The initial cost of raceways can be lower than conduit systems, but long-term costs may increase if they need to be modified or if they offer less protection in certain conditions.
Conduit: The installation of rigid conduit systems can be more labor-intensive and time-consuming compared to raceways. Metal conduit requires cutting, bending, and threading, which can increase installation time and costs. However, for high-risk environments or locations where physical protection is necessary, rigid conduit is often the preferred choice despite its higher upfront costs.
Labor Costs: Installing rigid conduit systems, particularly steel or aluminum, can significantly increase labor costs due to the complexity of fitting, threading, and installing. However, for long-term installations, the added durability and protection may justify the higher installation costs.
5.5 Future Flexibility and Maintenance
Future-proofing the electrical system to allow for easy upgrades or modifications is another important consideration. Some systems are easier to modify or maintain than others, depending on their design.
Raceways: One of the biggest advantages of raceways is their flexibility. Most raceways can be easily modified, extended, or upgraded, making them a great option for areas that require future changes or additions. The open structure of raceways allows for quick access to wiring, making maintenance easier and faster.
Example: In office buildings or commercial spaces, raceways like surface-mounted wiremold allow easy modification of wiring routes without requiring significant changes to the building structure.
Conduit: While conduit systems are more permanent, they can be challenging to modify once installed, especially for rigid types. However, flexible conduits (e.g., FMC) can provide the ability to adjust wiring paths with ease, offering more flexibility in temporary installations or environments where frequent changes are expected.
5.6 Aesthetic and Visibility
Aesthetic considerations might play a role in choosing between raceways and conduits, especially in commercial and residential spaces where the appearance of the wiring system matters.
Raceways: Surface-mounted raceways are visible and can often be integrated into the room’s design to minimize their appearance. Many raceways are available in a variety of colors and finishes, allowing them to blend into the environment or match the décor.
Conduit: Conduits are generally less aesthetically pleasing, especially when used in surface-mounted applications. However, they offer superior protection for wiring, which makes them preferable in industrial, outdoor, or high-risk environments.
6. Conclusion
Choosing between raceways and conduits is a complex decision that depends on a range of factors, including the type of installation, environmental conditions, safety requirements, budget, and maintenance needs. Raceways are typically easier and more cost-effective to install and are often used in surface-mounted, low-risk applications. On the other hand, conduits provide superior protection for wiring in harsher environments and are often required for underground or in-wall installations.

FAQs
1. What is the difference between electrical raceways and conduits?
The primary difference between electrical raceways and conduits is their structure and level of protection. Raceways are typically open systems that organize and route cables, while conduits are enclosed pipes or tubes that fully protect electrical cables from external damage. Raceways are often used for surface mounting and provide easier access to cables, while conduits are often buried or hidden within walls for added protection.
2. How do electrical raceways provide protection to cables?
While raceways do not fully enclose cables like conduit, they still provide some protection from physical damage, environmental factors (such as dust and moisture), and accidental wear. For example, a cable tray or duct keeps cables from becoming tangled, and surface-mounted raceways help prevent cables from being exposed to impacts or abrasion from surrounding objects.
3.How do I install electrical conduit?
The installation process can vary depending on the type of conduit, but generally involves these steps:
- Planning the Route: Map out where the conduit will run and measure the necessary lengths.
- Cutting the Conduit: Use a hacksaw, pipe cutter, or specialized tool to cut the conduit to the required lengths.
- Fitting and Connecting: Use connectors, elbows, and couplings to join sections of conduit. For rigid conduit, fittings must be threaded, while flexible conduit requires clamps or connectors.
- Securing the Conduit: Attach the conduit to walls, ceilings, or floors using conduit straps, clamps, or brackets.
- Pulling the Wires: Once the conduit is installed, carefully pull the electrical wires through the conduit using a fish tape or other wire-pulling tools.
