How to fix the corner of a cable tray

Use an adjustable corner or elbow joint inserted into the tray and secured with screws to create a smooth, protected inside corner for cables.Step-by-Step Guide1. Choose the Right Corner Accessory For inside corners, use an adjustable corner piece (SRS) or an elbow joint (RVS). These accessories fit inside the cable tray and allow you to adjust the angle, typically from 0° to 75° for SRS or -90° to +90° for RVS, depending on your layout ( ). 2. Prepare the Cable Tray Ensure the tray is clean, free of sharp edges, and properly aligned. Check that the tray sections leading to the corner are securely mounted using wall brackets, ceiling supports, or floor bases as appropriate ( ). 3. Insert the Corner Piece Slide the adjustable corner or elbow joint into the inside corner of the tray. Make sure it fits snugly and aligns with the tray sections on both sides. This ensures a smooth transition for cables and prevents sharp bends ( ). 4. Secure the Corner Use the included screw set to fasten the corner piece to the tray. Tighten screws evenly to avoid misalignment or gaps. Proper fastening ensures the corner remains stable under the weight of the cables ( ). 5. Protect and Route Cables Lay cables along the inside edges of the corner, avoiding sharp bends. Use cable ties, clips, or internal collars to secure cables and prevent movement. If the tray has rough edges, consider adding protective strips or padding to prevent insulation damage ( ). 6. Inspect and Test After installation, check that the corner is stable and that cables are not strained. Ensure the bend radius is within the cable manufacturer's specifications to avoid long-term damage ( ).Additional TipsPlan the Layout: Before installation, map out the tray path and corner angles to minimize tight bends.Use Modular Accessories: Adjustable corners simplify future expansions or modifications ( ).Select Appropriate Materials: For corrosive environments, use stainless steel or FRP; for indoor use, aluminum or PVC may suffice ( ). By following these steps, you can create a secure, smooth inside corner in your cable tray system that protects cables, maintains structural integrity, and allows for future adjustments.
