How to bend a mesh cable tray at a 45-degree angle

A 45-degree bend in a mesh cable tray is typically achieved by making two 22.5-degree cuts on separate tray sections, then joining them to form the desired angle.Step-by-Step Guide

1. Measure and Mark the Cuts

• Use a measuring tape and a protractor to mark a perpendicular line across the width of the tray.
• From this line, mark a 22.5-degree angle on each of the two tray sections. The second piece's cut should be in the opposite direction to the first to form a mitered joint . 2. Cut the Tray
• Use a bolt cutter or angle grinder with a metal cutting disc for precision and speed. Hacksaws are possible but slower and less accurate .
• Always wear safety goggles, gloves, and ear protection to prevent injury from metal shards . 3. Deburr and Protect Cut Edges
• Smooth all cut edges with a file or grinder to prevent cable damage.
• Apply cold galvanizing spray or anti-corrosion paint to protect the exposed metal from rust . 4. Bend the Tray
• For wire mesh trays, cut a V-shape from the side wires at the bend location.
• Carefully bend the tray at the cut to achieve the 45-degree angle. Reinforce the bend with couplers, brackets, or support arms if needed . 5. Join the Sections
• Align the two 22.5-degree cut sections to form a smooth 45-degree turn.
• Secure them using appropriate cable tray connectors or hardware to ensure stability and compliance with cable containment standards . 6. Support and Install
• Use compatible support arms, drop rods, or wall brackets at junctions or load-bearing areas to maintain structural integrity .
• Test-fit the assembly before final installation to ensure proper alignment and support.

Tips for Best Results

• Plan the route carefully to avoid obstacles and ensure smooth cable transitions.
• Maintain consistent spacing and alignment to prevent stress on cables.
• Follow manufacturer guidelines and local electrical codes for safety and compliance . By following these steps, you can create a precise 45-degree bend in a mesh cable tray while maintaining safety, structural integrity, and proper cable management.
