Do you have a diagram on how to cut a 45-degree cable tray

To create a 45-degree bend in a cable tray, make two 22.5-degree miter cuts on separate tray sections, then join them to form the angle.

Step-by-Step Instructions

1. Measure and Mark the Cuts

• Draw a perpendicular line across the width of the cable tray.
• Using a protractor or angle finder, mark a 22.5-degree angle from this perpendicular line on the first tray section.
• Repeat for the second tray section, but mark the 22.5-degree cut in the opposite direction to allow the two pieces to join and form a 45-degree bend . 2. Prepare the Tray
• Ensure the tray is clean and free of debris.
• Wear safety glasses, gloves, and ear protection to prevent injury from metal shards or sparks . 3. Cutting Tools
• Use an angle grinder with a metal cutting disc, a band saw, or a circular saw suitable for metal.
• For thin trays, a band saw is preferred for precision and minimal burrs.
• Avoid using torches, as they can weaken the metal and damage surface coatings . 4. Make the Cuts
• Cut along the marked 22.5-degree lines carefully.
• Ensure the tray is securely clamped to prevent movement.
• After cutting, deburr and smooth all edges to protect cables and prevent injuries . 5. Join the Sections
• Align the two cut sections so the angled edges meet, forming a 45-degree miter joint.
• Check the alignment and adjust slightly if necessary before securing the tray in place . 6. Optional: Test with Cardboard
• For first-time attempts, practice the cut on cardboard to verify measurements and angles before cutting the actual tray .

Tips and Considerations

• Always measure twice and cut once to avoid material waste.
• Maintain consistent spacing and alignment for multi-layer trays.
• Use proper PPE and follow local safety regulations when cutting metal trays.
• For complex installations, formulas like X = 0.414 × tray width can help calculate precise cut lengths for different tray sizes . By following these steps, you can achieve a precise 45-degree bend in a cable tray while ensuring safety and structural integrity.
