Specifications and Models of Cable Tray Fixing Brackets

Cable tray fixing brackets come in various models including stand-off, G hanger, trapeze, and wall-mounted types, with specifications depending on tray width, load, and material.

Common Bracket Types and Models

1. Stand-Off Brackets

• Used to mount cable trays or baskets at a specific distance from walls or surfaces.
• Sizes typically range from 50mm to 300mm.
• Example: 75mm Premier Stand-Off Bracket for trays up to 75mm wide, made from 2mm ribbed steel with hot-dipped galvanised (HDG) finish for corrosion resistance . 2. G Hanger Overhead Support Brackets
• Designed for overhead support of cable trays, trunking, or baskets.
• Available in sizes such as 100mm, 150mm, and 225mm.
• Constructed from 2mm thick pre-galvanised steel, with M10 top support holes for secure mounting . 3. Trapeze Support Brackets
• Pre-assembled for quick installation, providing robust support for wider trays.
• Widths: 100mm, 150mm, with drop lengths like 500mm.
• Materials include pre-galvanised steel, hot-dipped galvanised steel, and stainless steel (A316/A4) for durability . 4. Light Duty Wall-Mounted Brackets
• Example: Walraven Britclips® Master Clamp, suitable for light-duty cable trays.
• Designed for easy installation and high-quality support . 5. LBCEL Suspension Brackets
• Sizes: 9" (225mm) and 12" (300mm) for lightweight cable trays.
• Features M10 clearance holes and 6mm elongated slots for easy alignment.
• Can be fixed to walls or strut channels, supporting single or double studding applications.
• Optional LBCES01 end support adds extra stability for overhead installations .

Key Specifications to Consider

• Material: Steel (pre-galvanised or hot-dipped), stainless steel (A316/A4)
• Thickness: Typically 2mm for standard load-bearing brackets
• Mounting Holes: M10 or similar, sometimes with elongated slots for alignment
• Tray Width Compatibility: 50mm to 300mm depending on bracket type
• Load Capacity: Varies by model; check manufacturer datasheets for exact ratings
• Finish: Galvanised or stainless steel for corrosion resistance
• Packaging: Often sold in multiples (e.g., packs of 10) for convenience

Installation Notes

• Brackets can be mounted directly to walls, strut channels, or framing channels.
• Overhead brackets like G Hangers and trapeze supports are ideal for suspended cable trays.
• Stand-off brackets provide clearance from walls to allow airflow and cable access.
• Ensure compatibility with the cable tray system and verify load ratings for safety . These options provide flexibility for different installation environments, from light-duty wall-mounted trays to heavy-duty overhead support systems.
