How to connect a flexible cable tray

Flexible cable trays are connected using adjustable splice plates, clamps, or quick-connect systems to ensure secure, stable, and code-compliant installations.Tools and Materials NeededFlexible horizontal adjustable splice plates (furnished in pairs with hardware)Wrenches, spanners, or torque wrenchesMetal cutting tools or saws for field adjustmentsDrill (if additional holes are required)Cable tray supports (wall brackets, ceiling hangers, or trapeze supports)Step-by-Step Connection Process1. Plan the Route and Angle Determine the desired path and angle for the flexible cable tray. Mark the locations where the tray will be cut or adjusted to fit the installation ( ). 2. Prepare the Tray Sections Field cut the cable tray to the required length and remove any rungs that interfere with the cut. Ensure the ends are smooth and aligned for proper connection ( ). 3. Install Splice Plates Attach the flexible horizontal adjustable splice plates to the ends of the tray sections. These plates allow horizontal direction changes and provide a secure mechanical connection. Ensure supports are within 24 inches (600 mm) on both sides of the splice per NEMA VE2 standards ( ). 4. Secure with Fasteners Use bolts, nuts, and washers to tighten the splice plates. Torque the fasteners according to manufacturer specifications to ensure stability and prevent sagging ( ). 5. Check Alignment and Support Ensure the trays are level and properly aligned. Install additional supports if necessary to maintain stability, especially for long runs or heavy cable loads ( ). 6. Optional Quick-Connect Systems For faster installation, some manufacturers offer snap, slide, or twist connectors that require minimal tools. These are suitable for large projects but may be brand-specific ( ). 7. Final Inspection Verify that all connections are tight, the tray is level, and cables can be easily added or removed. Ensure compliance with local electrical codes and safety standards ( ).Tips for Flexible Cable Tray ConnectionsAlways measure and mark before cutting to avoid misalignment.Use supports close to splice points to prevent sagging.Avoid over-tightening bolts, which can deform the tray.Consider future maintenance and cable additions when planning connections. By following these steps, flexible cable trays can be securely connected, providing a durable, safe, and professional cable management system ( ).
