45-degree angle of the side of the cable tray

A 45-degree bend in a cable tray is typically achieved by making two 22. 5-degree cuts on separate tray sections and joining them to form the desired angle. Cutting and Forming a 45-Degree BendTo create a 45-degree angle in a cable tray, you generally use a mitered joint approach: Divide the angle: Each tray section contributes half of the total bend, so for a 45-degree turn, each piece is cut at 22.

5 degrees from a perpendicular line across the tray width. Marking: Use a protractor or angle finder to accurately mark the 22. 5-degree line on each tray section.

Cutting: Use an appropriate cutting tool, such as an angle grinder with a metal cutting disc, to make the cuts. Always cut away from the new end and ensure edges are smooth. Deburring: Smooth all cut edges to prevent cable damage and ensure safety during installation.

Joining: Align the two cut sections so the 22. 5-degree cuts face each other, forming a precise 45-degree bend. Secure with cable tray connectors and hardware.

Practical Considerations

Space constraints: A 45-degree bend is ideal for tight spaces where you need to change elevation or bypass obstacles quickly. Support: Ensure proper support at the top of the bend, especially for longer transitions, to maintain stability and prevent sagging. Testing: Before final installation, test-fit the pieces to confirm the angle and alignment.

Calculating Dimensions

For precise fabrication, you can calculate the cut lengths using the tray width and the desired angle: Measure from the centerline of the tray. Determine the distance to mark on each side for the miter cut. For example, in a 100 mm wide tray, a 45-degree bend requires 22.

5-degree cuts, which translates to approximately 41. 42 mm on each side from the centerline. Using cardboard or a mock-up first can help verify measurements before cutting the actual tray.

By following these steps, you can achieve a clean, functional 45-degree bend that maintains cable integrity and meets installation requirements.
