Cable tray tees are branch fittings that connect three tray sections, available in equal, unequal, horizontal, and vertical configurations to support efficient cable routing.

Overview of Cable Tray Tee Fittings

A cable tray tee fitting is designed to create a branch connection from a main cable tray route into one or more secondary routes while maintaining continuous cable support and structural integrity . Unlike bends, which change direction, tees allow cables to split efficiently, reducing the need for onsite modifications and improving installation quality .

Types of Cable Tray Tees

1. Equal Tees

• All three tray sections have the same width.
• Commonly used when the branch route requires the same capacity as the main tray.
• Simplifies installation and ensures uniform cable support . 2. Unequal Tees
• The branch section has a different width than the main tray.
• Ideal for situations where the branch carries fewer cables or a smaller load.
• Provides flexibility for future expansion or varying cable volumes . 3. Horizontal Tees
• All tray sections remain on the same elevation.
• Suitable for standard branching in equipment rooms, data centers, or commercial electrical systems . 4. Vertical Tees
• The branch rises above or below the main tray route.
• Useful for connecting trays across different floor levels or routing over obstacles .

Material and Finish Options

• Mild steel: Pre-galvanized (PG) or hot-dip galvanized (HDG)
• Stainless steel: Grade 1.4404 (316L) for corrosion resistance
• Aluminum or FRP: Lightweight and non-corrosive options for specialized environments

Applications

• Branching power or communication cables in data centers
• Distributing electrical circuits in industrial or manufacturing facilities
• Routing cables in commercial buildings or equipment rooms
• Supporting future expansion and maintenance access

Advantages

• Standardized solution reduces labor and installation errors
• Maintains continuous cable support and structural integrity
• Facilitates easy maintenance and future system upgrades
• Compatible with light, medium, and heavy-duty cable tray systems ranging from 50mm to 900mm in width By selecting the appropriate tee type—equal, unequal, horizontal, or vertical—engineers and contractors can ensure efficient cable management, safe installation, and long-term system reliability.
