The Application and Importance of Plain Electrical Clevis Hangers in Cable Management and Safety

What Is a Plain Electrical Clevis Hanger?

A plain electrical clevis hanger is a type of mechanical part used for fixing and securing electrical cables. This part is used in the installation and execution of wiring, especially in industrial and construction environments, to prevent unwanted movement of cables. Its design is such that it firmly grips the cables through two or more retaining claws and prevents them from bending or being pulled. The plain clevis hanger is usually made of materials such as metal or durable plastic to withstand pressure and various environmental conditions.

This type of clamp plays a vital role in power distribution systems as one of the main tools for better management of cables and wires. In addition, the plain clevis hanger offers easy and quick installation and, due to its simple structure, avoids additional costs. Other advantages include long service life, resistance to rust and corrosion (in metal versions), and the ability to bear the weight of cables.

In high-voltage power distribution systems and even in small domestic wiring, plain clevis hangers help maintain safety and organization in wiring. The use of these clamps, especially in construction and industrial projects, reduces possible damage to cables and prevents unwanted failures in the electrical system.

In What Environments Are Plain Electrical Clevis Hangers Used?

Plain electrical clevis hangers are used in a variety of environments that require the management, support, and safety of electrical cables. Among these environments, the following can be mentioned:

1. Industrial environments: In factories and heavy industries, where a large volume of cables is used to supply electrical power to machinery and equipment, plain clevis hangers are employed to secure and organize the cables.

2. Construction projects: In residential, commercial, and office buildings, these clamps are used to fix wires and cables along wall or ceiling electrical routes. They are also utilized in modern construction for managing network cables and security systems.

3. Outdoor environments: In the installation of overhead cables or in open environments, plain clevis hangers are used to protect cables against weather elements such as wind, rain, and temperature changes.

4. Underground environments and tunnels: In underground routes such as tunnels, mines, and sewer networks, these clamps are used to secure electrical cables to tunnel walls.

5. Electrical and telecommunications facilities: In electrical substations and telecommunication stations, these clamps play an important role in organizing and protecting power and data cables.

What Are the Applications of Plain Electrical Clevis Hangers?

Plain electrical clevis hangers have numerous applications in cable and wire management and safety. This component is used for securing, holding in place, and preventing unwanted movement of cables, and plays an important role especially in industrial and construction environments. Its main applications include the following:

1. Securing cables: The plain clevis hanger firmly holds electrical cables in designated paths to prevent their unwanted displacement and stretching. This is especially important in locations with a high volume of wiring.

2. Protecting cables: These clamps protect cables against physical damage such as excessive bending, abrasion, or external pressure. This prevents cable failure and consequently avoids electrical problems.

3. Creating order in wiring: By using clevis hangers, cables are placed neatly and orderly alongside each other. This organization helps improve cable management and facilitates future repairs and maintenance.

4. Preventing accidents: By securing cables and preventing them from hanging loose, the clevis hanger helps reduce the risks of electric shock or people tripping over cables.

What Material Are Plain Clevis Hangers Made Of?

In order for the plain clevis hanger to bear the weight of electrical conduits and cables at the heights of a structure, it must certainly be designed and manufactured from the strongest available alloys. Typically, steel sheets with controlled thickness are used for making these clamps. In fact, due to their high density, these alloys can support electrical conduits and cables with the highest level of safety. Steel alloys do not easily fracture, deform, or undergo structural changes.

For example, if aluminum material and other soft metals were used to make these parts, they would certainly disintegrate with the slightest force or pressure resulting from the weight. However, these mentioned issues do not exist with steel material. For this reason, the best material used for manufacturing plain clevis hangers is steel alloys and certain iron derivatives.

Why Are Plain Clevis Hangers Used?

To build power distribution networks, in addition to using electrical cables, we need other components such as electrical steel conduits. Of course, polymer or PVC versions of these conduits are also available, which are used in low-stress environments. However, we must consider that conduits need suitable connecting parts to remain stable within the structure.

As a general rule, two types of connectors can be considered for electrical conduits. One type is the fittings used between conduits, such as various elbows and similar items, and the next type are those that connect the conduits and the conduit network directly to the structure.

These parts are known as structural fittings. The plain clevis hanger also falls into the structural fittings group, meaning it acts as an intermediary part that connects steel electrical conduits to the structure. Of course, there are other complementary parts such as C-channels that must be used to complete the connection system. By reading the article on how to install clevis hangers, you can obtain more complete information.

The main purpose of using plain clevis hangers, as well as insulated types, is to be able to stabilize the conduits during the process of connecting them to the structure, thereby providing adequate safety for the conduit system. Of course, in such networks, clevis hangers are not alone, as other types such as Spit clamps and galvanized rods also exist in the conduit network, which can be used alongside clevis hangers for various purposes.

Generally, Spit clamps are used to create a suspended support for conduits. Plain clevis hangers, as well as insulated types, together with C-channels, and alongside various Spit clamps plus galvanized rods, provide the conditions for you to route and guide electrical conduits from the ceiling and wall areas in environments where there are architectural limitations. This is the sole purpose pursued for all types of electrical conduit fittings and cable connectors.

Standard Design of the Plain Clevis Hanger

In many international organizations responsible for assessing the standardization of industrial parts, it is always emphasized that all variables of a connecting part in conduit networks must be based on predetermined values. For example, the design of clevis hangers must be completely U-shaped. Therefore, a square angle cannot be created in the cross-section of the clamp.

On the other hand, a curved piece that is directly connected to the screw or movable lever of the clamp must have a suitable curvature based on the cylindrical structure of the pipe so that it can precisely help keep the pipes fixed. In addition, the sizing considered for the plain clevis hanger must be based on the pipe size. Therefore, we cannot arbitrarily consider any custom size for these clamps in the design process.

Other aspects such as the manufacturing material and the type of galvanized coating are all defined according to their own principles in standards assessment organizations. Therefore, if you visit a reputable manufacturing center to make a purchase, you can be confident that you have bought a high-quality and fully standard product.

Is the Plain Clevis Hanger Rustproof?

If strengthening elements are not applied to the plain clevis hanger, because they are made of metal alloys, they will suffer from rust and corrosion. One method of strengthening metal is the use of galvanized coatings on the parts. The hot-dip galvanizing process is among the methods used for strengthening metals. The clevis hanger is no exception to this rule and is coated under this mentioned process with molten zinc solutions.

Currently, subjecting metal parts to the hot-dip galvanizing coating process is one of the best and most ideal techniques for rustproofing metals. With this valuable feature, you can use these clamps even in open environments exposed to weather and in industrial spaces with high humidity.

What Is the Structure of the Plain Clevis Hanger?

As mentioned, the plain clevis hanger has a U-shaped structure. In the central upper part of the clamp, a lever or screw is installed, the end of which is connected to a curved surface. When you move the lever or screw, it is guided downward or upward. By turning this lever, you can fix the electrical conduits and cables completely stably and motionlessly in place. At the lower part of the clamp, there is a claw-like or toothed structure, through which this specific curved shape can create a strong and secure connection.

In addition to plain types, there are also insulated clevis hanger models used for various types of electrical cables. Whether you use plain or insulated models depends on the type of electrical conduit or cabling network. Insulated types are mainly used for the direct support of electrical cables. Due to the use of a plastic layer inside the clamp, it practically causes no damage to the texture or outer sheath of the cables.

How Does the Support Mechanism of These Clamps Work?

The support mechanism of the plain clevis hanger is such that to use it, we need a C-channel rail or clevis hanger rail. These rails are classified in long lengths of one to three meters. Due to their C-shaped structure, they can accommodate these clevis hangers and complete the support system for electrical conduits and cables. You can use several plain clevis hangers along the axis of the C-channels.

Given the strong metal structure of these rails, they can provide the safest power cable support network at the heights of a structure. You can attach the rails directly to the ceiling or wall. By doing so, electrical conduits and cables can be routed from both the wall area and the ceiling area. Of course, one of the functions of C-channel rails is to accept various types of clevis hangers, but they have numerous other applications as well, such as creating support systems for various types of cable trays and cable ladders, and they can also be used together with various types of Spit clamps.

Paying Attention to Clamp Size

The plain clevis hanger has a very high variety in terms of size. As you know, electrical conduits and cables are not supplied in a single size; rather, they also have a wide range of sizes. To support them, we need to use clamps that have a coordinated and appropriate size. Generally, because clevis hangers have a movable screw, they can cover a specific size range. This size range is often referred to as the grip diameter, which indicates support for a range of electrical conduit and cable sizes.

The minimum grip diameter of clevis hangers is 8 to 12 millimeters, and the maximum grip diameter of these parts is 44 to 48 millimeters. Of course, other sizes can also be custom-designed for various industrial projects. To explain further, when we say the grip diameter of a clamp is 8 to 12 millimeters, it means it has the capability to support electrical conduits and cables that fall within this size.
