Cable tray cut at a right angle to the wall

To cut a cable tray at a right angle to a wall, use appropriate tools like bolt cutters or an angle grinder, ensure smooth edges, and reinforce the cut section with brackets or couplers for safe wall-mounted installation.Tools and Preparation

For wire mesh or metal cable trays, the most effective tools are bolt cutters or an angle grinder. These provide a clean cut and minimize the risk of sharp edges that could damage cables or injure installers . While a hacksaw can be used, it is slower and less precise . Always wear safety goggles and gloves to protect against metal shards.

Cutting Technique

1. Measure and mark the exact point where the tray meets the wall.
2. For wire mesh trays, you can cut a V-shape from the side wires to allow bending at a right angle .
3. For solid metal trays, cut straight across the tray at the marked line using the chosen tool .
4. Ensure the cut edges are smooth or deburred to prevent cable damage.

Bending and Fitting

• After cutting, bend the tray carefully to form a 90° angle if needed. Wire mesh trays can often be bent by hand or with pliers, while metal trays may require a bending brake or careful manual adjustment .
• Use fabricated wall sleeves or corner brackets to provide rigid support where the tray meets the wall .

Reinforcement and Support

• Install compatible wall brackets, support arms, or drop rods at the junction to maintain load-bearing capacity .
• For wire mesh trays, consider couplers or clamps to reinforce the bent section and maintain structural integrity .
• Ensure the installation complies with manufacturer guidelines and local electrical codes.

Finishing

• If the tray is coated, consider touching up the cut edges with paint or protective coating to prevent corrosion .
• Verify that the tray is level and securely fastened before laying cables. By following these steps, you can achieve a clean, safe, and structurally sound right-angle cut for wall-mounted cable trays, suitable for both wire mesh and solid metal types.
