How to make right angles in cable trays

Yes, cable trays can be fabricated to form right-angle (90°) bends using calculated cuts and bends.Fabricating 90° BendsCable trays are designed to be flexible in routing, allowing horizontal, vertical, or compound changes in direction to navigate obstacles . To create a 90° bend, the tray is typically cut and bent in sections. For example, a sweeping 90° bend can be made using two 45° bends or three 30° bends, depending on the tray width and desired smoothness of the curve . The central section between bends is calculated using the tray width and trigonometric formulas, such as the square root of 2 times the width squared for a 45° set .Cutting and Safety ConsiderationsWhen cutting cable trays for bends, it is important to use appropriate tools such as band saws, circular saws, or angle grinders, while following safety precautions like wearing gloves, eye protection, and ensuring proper handling to avoid sharp edges . Burrs should be removed after cutting to maintain safety and ease of cable installation .Offsets and Complex RoutingCable trays often need to navigate around obstacles, requiring horizontal, vertical, or compound offsets. Horizontal offsets shift the tray left or right, vertical offsets raise or lower it, and compound offsets combine both movements . Calculations for offsets ensure smooth cable pulling and compliance with bending radius requirements, which is critical for thick or high-voltage cables .Practical TipsMeasure the tray width and calculate the cut-out sections accurately before bending .Use modular fittings like T-pieces, cross-overs, or reductions for complex routing .Test the first bend on-site to verify dimensions before completing the full installation . By following these methods, cable trays can be effectively routed at right angles while maintaining structural integrity and safe cable management.
