Tutorial on making cable tray tee

Cable tray tees can be created on-site using wire mesh trays with bolt cutters or specialized tee kits, allowing for quick and safe junctions in cable management systems.

On-

Site Assembly Using Wire Mesh TraysFor wire mesh cable trays, tees can be formed directly at the project site without pre-fabrication. The process involves: Cutting the Tray: Use a bolt cutter to cut the straight section of the wire mesh tray where the tee will branch. The cutter drags a layer of zinc across the cut end, forming a protective layer that prevents corrosion.

Forming the Tee: Bend the cut section to create a 90-degree branch. Rubber caps can be applied to exposed ends for additional safety and protection. Securing the Junction: Fasten the intersecting sections using bolts or hardware provided in assembly kits.

This ensures structural integrity and maintains proper cable support.

Using Specialized Tee Kits

Some manufacturers offer EZT 90 Kits or similar hardware kits designed specifically for making tees in wire mesh trays: The kit includes all necessary hardware for one tee or two 90-degree bends. It simplifies installation, especially for installers who are new to wire mesh cable trays. The kit ensures proper alignment and secure fastening, reducing the risk of damage to cables or the tray itself.

Safety and Best Practices

Always follow manufacturer guidelines and local electrical codes when forming tees. Ensure that the tray is properly supported at the junction to handle cable weight. Avoid using cable trays as walkways or supports for personnel, as this can cause injury and damage the system.

Check that all cut edges are protected with caps or zinc coating to prevent injury and corrosion.

Summary

Creating a cable tray tee can be done either live on-site using bolt cutters and wire mesh trays or with specialized tee kits for precise and secure junctions. Proper cutting, bending, and fastening, along with safety measures like protective caps, ensure a reliable and durable cable management system.
