Thickened Triangular Support for Cable Trays

Thickened triangular supports provide enhanced stability and load-bearing capacity for cable trays, ensuring secure and organized cable routing in industrial and commercial installations.

Overview

Thickened triangular supports, also known as triangle wall support brackets, are designed to secure cable trays or ladders to walls or other structural surfaces. Their triangular shape distributes weight efficiently, reducing sagging and stress on the tray while supporting heavy cable loads. These supports are commonly used in AV setups, industrial plants, tunnels, and power stations where high mechanical strength and stability are required .

Material and Construction

• Typically made from high-quality low-carbon steel or galvanized steel for durability and corrosion resistance .
• Can feature pre-galvanized or hot-dip galvanized finishes to withstand indoor and outdoor environments .
• Some designs include thickened metal plates at the triangle's base and apex to enhance load-bearing capacity and prevent deformation under heavy cable loads .
• Standard lengths and widths vary, with custom sizes available to accommodate specific tray dimensions and installation requirements .

Load Capacity and Span

• Triangular supports are engineered to handle significant loads, often supporting up to 280 lbs per foot depending on spacing and tray type .
• Proper installation requires supports to be spaced according to tray width and cable weight, typically every 8 feet for horizontal runs, with additional supports near expansion joints or fittings .
• The thickened design allows for larger spans between supports without compromising stability, making them suitable for wide or heavily loaded cable trays .

Installation Considerations

• Supports can be mounted using anchors (M10, M12, M16) for concrete walls or hex bolts for C-channel frames .
• Wall-mounted triangular brackets often include pre-drilled slots for flexible attachment points, simplifying alignment and installation .
• For vertical or horizontal cable routing, supports should be positioned to avoid placing connectors or splice joints directly at the support point, ensuring even load distribution .
• Some systems, like the E-KLIPS range, allow drill-free installation using clamps or yokes, saving time while maintaining high load capacity .

Advantages

• Enhanced load distribution reduces stress on cable trays and prevents sagging.
• Corrosion-resistant finishes extend service life in harsh environments.
• Flexible mounting options accommodate various wall types and structural frames.
• Compatibility with multiple tray types, including wire mesh, ladder, and solid-bottom trays. Thickened triangular supports are a reliable solution for heavy-duty cable management, providing both structural integrity and ease of installation in demanding industrial and commercial applications .
