How to cut corners on cable trays

Corners of cable trays can be cut and bent on-site using proper marking, cutting tools, and safety precautions to ensure smooth transitions and maintain tray integrity.Steps for Cutting Cable Tray Corners1. Plan and Measure: Before cutting, measure the exact location of the corner and mark the cut line clearly using a marker or chalk. Ensure the bend radius is appropriate for the cables you will run, especially for Ethernet or fiber optic cables, to prevent damage . 2. Choose the Right Tools:Wire Mesh Trays: Can be cut with hand tools like bolt cutters or a hacksaw for small adjustments, or a grinder for precise cuts .Metal or Ladder Trays: Use a band saw, circular saw, or angle grinder with a suitable blade for the material thickness. Avoid torches as they can weaken the metal and damage surface coatings . 3. Cutting Technique:Secure the tray firmly to prevent movement.Follow the marked line carefully, cutting slowly to maintain a clean edge.For mesh trays, strategic side cuts allow smooth corner transitions without sharp bends .For metal trays, use a blade guard and handle tools with both hands to reduce injury risk . 4. Deburring and Finishing: After cutting, remove any sharp edges or burrs using a file or deburring tool to prevent cable damage and ensure safety . 5. Safety Precautions: Always wear Kevlar gloves, safety glasses, and appropriate PPE. Protect surrounding materials from sparks if using grinders or saws . 6. Verify Installation: After cutting and bending, check that the tray maintains structural integrity, proper grounding, and that cables can pass through corners without stress . Avoid overfilling trays at corner sections to maintain airflow and cable organization. By following these steps, you can safely and efficiently cut corners in cable trays, whether mesh or metal, ensuring a professional installation that accommodates tight spaces and structural constraints .
