Upper left tee of cable tray

An upper left tee is a cable tray fitting that allows a branch to extend from the main tray at a left-hand angle, typically connecting three tray sections.

Function and Configuration

The upper left tee is used to create a junction where a main cable tray run splits into a branch on the left side while maintaining the main run. It is commonly employed in electrical and data cabling systems to route cables efficiently around corners or to equipment. The tee can be equal or unequal, depending on whether the branch and main tray widths are the same or different.

Dimensions and Ordering

When ordering a cable tray tee, you should specify the widths of the three connecting sections, typically denoted as W1 x W2 x W3, where W1 and W2 are the main run widths and W3 is the branch width. Material options include steel, aluminum, or stainless steel, often with finishes like hot-dip galvanized, powder-coated, or bare metal, chosen based on environmental conditions and corrosion resistance requirements.

Installation Considerations

Ensure the tee is properly supported to handle the cable load. Maintain the minimum bend radius for cables exiting the tee to prevent damage. Use covers or ventilated designs if required for heat dissipation or electromagnetic interference protection.

Verify compatibility with the main tray system, including load class and mounting method (floor, wall, ceiling, or rack),.

Summary

The upper left tee is a versatile cable tray fitting that enables branching to the left from a main tray run. Proper selection of width, material, and support ensures safe and efficient cable management in industrial, commercial, or data center environments.
