Cable tray fixing brackets are available in a range of sizes, typically from 50mm to 300mm, with mounting holes designed for M10 bolts or similar fasteners.

Standard Bracket Sizes

Cable tray brackets are manufactured to accommodate different tray widths and installation types:

• Stand-Off Brackets: Provide clearance from walls or surfaces, available in sizes from 50mm to 300mm .
• G Hanger Support Brackets: Used for overhead support, commonly available in 100mm, 150mm, and 225mm widths .
• Trapeze Support Brackets: Pre-assembled for overhead installations, with widths like 100mm, 150mm, and drop lengths up to 500mm .
• Lightweight Wall-Mount Brackets: For smaller trays, sizes such as 225mm (9") and 300mm (12") are common, with M10 clearance holes and elongated slots for alignment .

Mounting and Fixing Details

• Bolt Holes: Most brackets use M10 clearance holes for secure attachment, with some designs including 6mm elongated slots to allow easy alignment .
• Material and Thickness: Brackets are typically made from pre-galvanized steel, hot-dipped galvanized steel, or stainless steel (A316/A4), with thicknesses around 2mm for standard support .
• Compatibility: Brackets are designed to fit standard cable trays and baskets, ensuring proper load distribution and structural integrity .

Additional Considerations

• Load Capacity: Bracket selection should consider the weight of the cable tray and cables, as well as spacing between supports.
• Installation Flexibility: Some brackets allow side loading of cables or direct attachment to walls or strut channels .
• Corrosion Resistance: For outdoor or harsh environments, hot-dipped galvanized or stainless steel brackets are recommended . By selecting the correct bracket size and type, installers can ensure secure, durable, and compliant cable tray installations suitable for both wall-mounted and overhead applications.
