French cable tray bends can be installed on-site using bolt cutters or pre-fabricated fittings, ensuring proper bend radius, structural support, and corrosion protection.

Tools and Materials

To install cable tray bends, you will need:

• Bolt cutters for live bending of wire mesh trays .
• Rubber end caps to protect cut ends and maintain safety .
• Fasteners or Swiftclip systems for quick assembly of medium to heavy-duty trays .
• Support brackets to maintain tray alignment and prevent sagging .

Creating Bends On-Site

Wire mesh cable trays can be bent directly at the project site:

• Use a bolt cutter to cut and shape the tray. The cutting process drags a layer of zinc across the cut, forming a protective layer against corrosion .
• After cutting, apply rubber caps to exposed ends to prevent injury and maintain protection .
• Ensure the minimum bend radius is respected to avoid damaging cables, especially for instrumentation and control applications .

Installing Pre-Fabricated Bends

For ladder, channel, or solid-bottom trays:

• Select the appropriate pre-fabricated bend (45°, 90°, or custom angles) based on the routing requirements .
• Attach bends using fast-fit connectors or bolts, ensuring alignment with the main tray run .
• Maintain proper rung spacing (typically 150–230 mm) to support cables and prevent sagging .

Structural Support and Safety

• Ensure all bends and trays are supported according to load requirements, including future cable additions .
• Avoid cutting or drilling structural building members without approval .
• Use corrosion-resistant materials such as galvanized steel or aluminum to protect against environmental exposure .

Best Practices

• Plan the tray route to minimize sharp bends and maintain smooth cable transitions.
• Use integrated fasteners like Swiftclip for faster installation and reduced component count .
• Verify that bends do not exceed deflection limits and that cables maintain proper spacing and protection . By following these steps, French cable tray bends can be installed efficiently, safely, and with long-term durability, whether using live bending techniques or pre-fabricated fittings.
