Cable tray tees are available in equal and unequal types, for light, medium, and heavy duty systems, with prices typically ranging from £20 to £150 depending on size, material, and finish.

Types of Cable Tray Tees

1. Equal Tees: These tees have all three branches of the same width, ideal for symmetrical cable splits in a system . 2. Unequal Tees: These have one branch narrower than the other two, suitable for connecting a smaller cable run to a main tray . 3. Crossovers: While not strictly tees, crossovers allow two cable runs to intersect smoothly and are often used alongside tees for complex layouts . Duty Ratings:

• Light Duty: For smaller cable loads, typically in office or residential installations .
• Medium Duty: Common in commercial buildings, supporting moderate cable weight .
• Heavy Duty: Designed for industrial or high-capacity installations, supporting large bundles of cables . Materials and Finishes:
• Mild Steel Pre-Galvanised (PG): Standard, cost-effective option .
• Mild Steel Hot-Dip Galvanised (HDG): Offers enhanced corrosion resistance .
• Stainless Steel Grade 1.4404 (316L): High corrosion resistance for harsh environments, available to order . Sizes: Widths range from 50mm to 900mm, with depth and height options varying by manufacturer .

Prices

• Pre-Galvanised Medium Duty Equal Tee: Approximately £20–£50 for smaller sizes (e.g., 100–300mm width) and £50–£100 for larger widths .
• Hot-Dip Galvanised or Stainless Steel Tees: Prices can range from £80 to £150 depending on size and material .
• Unequal Tees and Crossovers: Typically slightly higher than equal tees of the same size due to custom dimensions .

Additional Considerations

• Covers: Closed or ventilated covers are available for all tees, adding protection and airflow management .
• Compatibility: Ensure the tee matches the tray system in width, depth, and duty rating. Accessories like bends, risers, and couplers may be needed for a complete installation .
• Suppliers: UK-based suppliers include Metsec, Shop4 Electrical, and TradeSparky, offering online ordering and delivery . By selecting the appropriate type, material, and size, cable tray tees can provide a durable and organized solution for branching cable runs in any electrical installation.
