How to make an electrical cable tray tee

An electrical cable tray tee can be made by cutting, bending, and joining straight tray sections using gussets, brackets, or specialized kits to form a T-shaped connection. Fabrication Methods1. Using Gusset Tees A gusset tee involves creating a T-shaped section by cutting the main tray and adding a gusset to support the branch.

Measure the branch location carefully, cut the side walls of the main tray, and attach a gusset plate to reinforce the connection. This method ensures structural stability and is suitable for metal trays where welding or bolting is possible. 2.

Using Brackets and Accessories Some cable tray systems, like EzyTray, allow you to fabricate a tee without pre-made fittings. Cut the side wall of the tray where the branch will connect, bend it down, and attach a TX bracket on each side. Use splice plates and bolts to secure the connection, ensuring the tray is supported at least twice along its length.

3. Using Tee Kits For wire mesh trays, kits like the EZT 90 Kit provide all necessary hardware to create a 90-degree tee. The kit includes brackets and fasteners for one tee or two bends, simplifying installation and ensuring proper alignment.

Steps for a Basic Tee FabricationMeasure and mark the location for the branch on the main tray. Cut the tray side walls and bottom as needed to accommodate the branch. Bend or shape the branch tray section to fit the tee configuration.

Attach gussets or brackets to reinforce the joint. Secure with bolts or screws, ensuring smooth edges to prevent cable damage. Check alignment and support the tray adequately to maintain structural integrity.

Tips

Always use two splice plates per tray length for stability. Smooth-headed bolts should face inward to avoid damaging cables. Ensure riser links or brackets are installed in pairs for proper support.

Verify that the tee maintains the minimum bend radius for cables exiting the tray. By following these methods, you can create a reliable and safe cable tray tee suitable for various electrical installations.
