How to cover the cable tray tee

Fiber and communications infrastructure knowledge brief Published 06 Apr 2026

Use this reference to prepare product questions for CJC FIBRE. Check interfaces, capacity, protection and installation requirements against the current product documentation.

A cable tray tee cover can be fabricated by measuring the tee dimensions, selecting a suitable material, cutting and shaping the cover, and securing it with bolts or hinges for easy access. Step 1: Measure the TeeBegin by measuring the width, length, and height of the cable tray tee where the cover will be installed. Accurate measurements ensure the cover fits snugly over the junction without interfering with the cables inside.

Step 2: Choose the MaterialSelect a material compatible with the cable tray and the environment. Common options include steel, aluminum, fiberglass, or composite materials. Metal covers are durable and suitable for industrial environments, while fiberglass or composite covers are lightweight and corrosion-resistant.

Step 3: Cut and Shape the CoverUsing the measurements, cut a sheet of the chosen material to form the top and side flanges of the cover. The cover can be flat, dome-shaped, or corrugated depending on the application and protection requirements. Dome or peaked designs help prevent debris accumulation.

Step 4: Form the FlangesBend the edges of the cover to create flanges that will rest on the tee edges. Flanges provide stability and allow the cover to be bolted or clamped securely. Step 5: Attach the CoverSecure the cover to the tee using bolts, screws, or hinge mechanisms.

Hinged covers allow easy access for maintenance, while removable covers can be lifted off when needed. Ensure that fasteners do not damage the cables inside; smooth-head bolts or protective washers are recommended. Step 6: Optional Protective CoatingFor outdoor or corrosive environments, consider applying a protective coating such as powder coating, galvanization, or paint to extend the cover's lifespan.

Tips

Always allow enough clearance for cables to pass without being pinched. Use splice plates or brackets if fabricating the tee from straight tray sections to ensure structural integrity. Check that the cover is easily removable for future cable maintenance or inspection.

By following these steps, you can create a custom-fit, durable cover for a cable tray tee that protects cables from dust, moisture, and physical damage while maintaining accessibility.
