How to cut the angle of the cable tray

To cut a cable tray for an angled bend, use mitered cuts on two sections, each cut at half the desired angle, and ensure proper marking, cutting, and deburring for safety and precision.Step-by-Step Guide for Angled Cuts1. Determine the Angle: For a 45-degree bend, each section of the cable tray should be cut at 22.5 degrees from a perpendicular line across the tray's width. This creates a mitered joint that forms the desired angle when joined . 2. Mark the Cut Line:Use a measuring tape to measure the exact location of the cut.Draw a perpendicular line across the tray width.Use a protractor or angle finder to mark the 22.5-degree angle from the perpendicular line on each tray section. Ensure the second piece's cut is in the opposite direction to the first . 3. Select the Cutting Tool:Band saw: Ideal for thin metal trays, providing clean cuts with minimal burrs .Circular saw: Suitable for light trays; cordless models with chip collectors improve safety and precision .Angle grinder: Offers flexibility but produces more sparks and requires careful handling with both hands . Avoid torches as they can damage the tray's surface and weaken the material . 4. Secure the Tray: Clamp the tray firmly using clamps or a vise to prevent movement during cutting . 5. Execute the Cut: Cut along the marked line carefully, maintaining a steady hand and following the angle precisely. Ensure the blade is appropriate for the tray material (metal or fiberglass), . 6. Deburr and Smooth Edges: After cutting, use a deburring tool or metal file to remove sharp edges. This prevents injury and protects cables from damage during installation . 7. Safety Precautions: Always wear safety glasses, gloves, and hearing protection. Kevlar gloves are recommended for handling cut edges, and ensure the surrounding area is protected from sparks if using grinders .Tips for Accuracy and EfficiencyDouble-check measurements before cutting.Use cutting oil for thicker trays to prolong blade life and reduce heat .For complex bends, consider creating a template to ensure consistent angles across multiple sections. By following these steps, you can achieve precise angled cuts on cable trays while maintaining structural integrity, safety, and compliance with installation standards .
