Installation of Corner Brackets for Cable Trays

Cable tray corner brackets are installed by aligning the bracket with the tray ends, securing with appropriate fasteners, and ensuring level and stable support for smooth cable routing.Step-by-Step Installation1. Plan and Mark the Route Before installing the corner bracket, review the approved shop drawings to determine the tray layout and corner locations. Mark the exact positions on the wall, ceiling, or support structure where the bracket will be mounted, ensuring proper clearance and alignment with the rest of the tray system . 2. Prepare the Support System Use threaded rods, Unistrut channels, or other support structures to carry the load of the trays. Cut the rods and channels to the required length, leaving extra space for adjustments . Ensure that the support system is level and capable of handling the combined weight of the trays and cables . 3. Position the Corner Bracket Place the corner bracket at the intersection of the two tray sections. Align it so that the trays will meet at the correct angle (typically 90° for standard corners). The bracket should sit flush with the tray edges to maintain a smooth cable path . 4. Secure the Bracket Attach the bracket using the recommended fasteners, such as hex nuts, bolts, or spring nuts, depending on the tray type and manufacturer instructions. Ensure that washers are used where necessary to distribute the load and prevent damage to the tray . Tighten the fasteners securely but avoid over-tightening, which could deform the tray. 5. Check Alignment and Level After securing the bracket, verify that the trays are level and properly aligned. Adjust the bracket or support system as needed to maintain a continuous, straight path for cable installation . 6. Install Tray Sections Slide the tray sections into the corner bracket, ensuring they are fully seated and supported. Use additional tray clips or hold-down brackets if required to prevent movement and maintain structural integrity . 7. Final Inspection Perform a final check to ensure all fasteners are tight, the bracket is stable, and the trays are properly aligned. Confirm that the installation meets load requirements and safety standards, including grounding and bonding if using metal trays .Tips for Best PracticeUse brackets and fittings from the same manufacturer to ensure compatibility .Maintain proper support spacing (typically 1.5–3 meters) to prevent sagging .Allow for future adjustments by leaving slight clearance in the bracket installation .Label and document the installation for maintenance and troubleshooting . By following these steps, the cable tray corner bracket will provide a secure, stable, and safe transition for cables around corners, ensuring long-term reliability of the cable management system.
