Cable tray tee types and names

Cable tray tees are commonly referred to as equal tees, unequal tees, horizontal tees, vertical tees, and sometimes as branch or crossover fittings depending on configuration and application.

Common Types of Cable Tray Tees

Equal Tee: This type has all three branches of the same width, allowing a uniform split from the main tray into two secondary routes, ideal for balanced cable distribution . Unequal Tee: Features a main tray branch wider than the side branch, used when the secondary route carries fewer cables or requires a smaller tray width . Horizontal Tee: Maintains all three tray sections on the same elevation, creating a branch on the same plane as the main tray . Vertical Tee (Riser Tee): Creates a branch that rises above or drops below the main tray route, useful for multi-level installations or when routing over obstacles . Crossover Tee: Sometimes used interchangeably with tees, these fittings allow one tray to cross over another while maintaining cable support, often in complex layouts .

Material and Finish Variations

Cable tray tees are available in mild steel (pre-galvanized or hot-dip galvanized) and stainless steel (grade 316L), with options for closed or ventilated covers depending on environmental and load requirements .

Applications

Tees are essential for branching cable routes in data centers, commercial electrical systems, manufacturing facilities, and equipment rooms. They simplify installation, maintain cable support, and allow for future expansion without field modifications .

Summary

In practice, cable tray tees may be referred to by their branch configuration (equal or unequal), orientation (horizontal or vertical), or function (branch or crossover). Selecting the correct type ensures efficient cable routing, structural integrity, and compliance with installation standards .
