Right-angle bend in mesh cable tray

Right-angle bends in wire mesh cable trays can be made safely by cutting specific wires, bending the tray gradually, and reinforcing the bend to maintain strength.

Tools and Preparation

To make a 90° bend, you will need: Bolt cutters or wire cutters to cut selected mesh wires without compromising tray integrity. Protective gloves to prevent injury from sharp edges. Measuring tools to mark precise bend points.

Reinforcement clamps or connectors to maintain structural strength at the bend.

Step-by-

Step Process for a Horizontal 90° BendMark the Bend Location: Identify where the tray needs to turn and mark the wires that will be cut. Cut Selected Wires: Using bolt cutters, cut the wires at the bend line. Avoid cutting all wires completely to maintain tray stability.

Bend the Tray: Gradually bend the tray to a 90° angle. Apply even pressure to avoid kinks or sharp edges that could damage cables. Reinforce the Bend: Use clamps or connectors to secure the bend and restore load-bearing capacity.

Check for Smoothness: Ensure the bend is smooth and free of sharp protrusions to prevent cable damage.

Vertical Bends

Vertical Inside Bend: Bends upward to move cables from a lower to a higher level. Ensure a smooth transition to minimize stress on cables. Vertical Outside Bend: Bends downward to guide cables from a higher to a lower level.

Maintain proper support at the bend point.

Tips for Safe and Professional Bends

Avoid cutting all wires completely; leave some intact for strength. Use rubber caps or protective covers on cut ends to prevent injury and maintain protection against corrosion. Follow manufacturer guidelines for specific tray types to ensure warranty and performance.

Reinforce sharp bends to prevent sagging or deformation under cable load. By following these steps, you can create clean, durable right-angle bends in wire mesh cable trays, ensuring safe and efficient cable routing for your installation.
