How to make a side bend in a cable tray

To install a side bend in a cable tray, cut and bend the tray carefully, maintain the proper radius, and secure it with splice plates and bolts to ensure stability and cable protection.Step-by-Step Installation1. Plan the BendDetermine the angle and location of the side bend.Ensure the bend radius is sufficient for the type of cables (Ethernet, fiber, or power) to prevent damage or signal interference . 2. Prepare the TrayFor steel trays, you can use a cable tray bending machine or a simple metal bar to create the bend if a pre-manufactured fitting is unavailable .For wire mesh trays, make strategic side cuts along the tray to allow smooth corner transitions . 3. Cutting and BendingUse appropriate tools: a bolt cutter or angular blade cutter for mesh trays, or a crimping tool for steel trays .Position the tray open side down for optimal cutting and bending angles.Bend the side wall gradually to avoid kinks or sharp edges that could damage cables . 4. Securing the BendUse splice plates (two per tray length) and SBH or CNH splice nuts and bolts to fasten the bent section securely .Ensure the smooth head of the bolts faces inward to prevent cable abrasion.For risers or external bends, install riser links in pairs, one on each side of the tray . 5. Final ChecksVerify that the bend maintains the proper radius and that cables can pass through without obstruction.Check grounding and bonding after modification to ensure electrical safety .Avoid overfilling the tray at the bend to maintain airflow and prevent overheating . 6. Optional TipsFor complex layouts, use TX brackets to fabricate tees or crosses by cutting and bending the side walls, then attaching the bracket on both sides .Always secure the tray at least twice along its length to maintain stability . By following these steps, you can safely and efficiently install a side bend in a cable tray while protecting cables and ensuring structural integrity.
