Complete Guide to Cable Tray Support Styles

Cable trays can be supported using hangers, wall brackets, floor-mounted supports, Unistrut systems, or vertical supports, depending on space, load, and installation requirements. Common Cable Tray Support Methods1. Hanger Supports Hanger supports suspend cable trays from ceilings or overhead structures.

They are ideal for areas with limited floor space and allow adjustable positioning to accommodate different tray sizes and cable loads. Hangers help maintain clear floor space while keeping cables organized and accessible for maintenance. 2.

Wall-

Mounted Supports Wall brackets attach cable trays directly to walls, making use of existing vertical surfaces. This method is commonly used in data centers, industrial facilities, and corridors where ceiling suspension is not feasible. Wall-mounted supports provide stability and keep cables off the floor.

3.

Floor-

Mounted Supports Floor-mounted brackets or pedestals are used when ceiling or wall mounting is impractical. They are suitable for large industrial areas, long corridors, or open spaces where cable trays need to run along the floor. These supports can handle heavy cable loads and provide a stable base.

4. Unistrut Systems Unistrut channels are versatile support systems that can be installed from the ceiling, wall, or floor. They offer high strength and flexibility, allowing easy adjustment of tray positions and accommodating complex routing paths.

Unistrut systems are widely used in commercial and industrial installations. 5. Vertical Supports Vertical supports are used for cable trays that need to run between floors or change elevation.

They maintain cable organization and prevent sagging during vertical transitions, ensuring safe and reliable cable routing in multi-story buildings.

Additional Considerations

Support Spacing: Proper spacing between supports is critical to prevent sagging and overloading. The distance depends on the tray type, cable weight, and environmental conditions. Material and Corrosion Protection: Supports are typically made of steel or stainless steel, with galvanization or coatings applied for corrosion resistance, especially in industrial or outdoor environments.

Accessories: Mounting plates, clamps, and other accessories may be used to secure junction boxes, devices, or covers to the tray system. By selecting the appropriate support method and spacing, cable tray systems can achieve maximum safety, organization, and accessibility, while accommodating future maintenance and upgrades.
