A multi-cable tray tee is connected by aligning the three tray sections, using the appropriate connectors or couplers, and securing them with bolts or proprietary kits to ensure structural integrity and continuous cable support.

Step-by-Step Connection Process

1. Prepare the Tee and Tray Sections Ensure that the tee fitting and the three cable tray sections are compatible in size and type (ventilated, solid, or wire mesh). Check that the tray ends are clean and free of burrs or debris to allow proper alignment and connection . 2. Align the Tray Sections Position the main tray and the branch tray ends to the tee fitting. The tee has three connection points: one for the main run and two for the branch or side runs. Make sure all tray ends are flush and properly aligned to prevent sagging or uneven load distribution . 3. Select the Appropriate Connectors Use couplers, splice kits, or proprietary connector kits recommended by the tray manufacturer. For wire mesh or heavy-duty trays, bolt sets or clip systems are commonly used to secure the sections together . Ensure the connectors match the tray type and load rating. 4. Secure the Connection Attach the connectors at each junction point. For bolted connections, insert bolts through the pre-drilled holes in the tray and tee, then tighten to the manufacturer's torque specifications. For clip or tool-less systems, ensure the clips fully engage and lock the tray ends in place . 5. Verify Structural Integrity Check that the tee is level and that all three tray sections are firmly connected. Ensure there is no misalignment, which could cause uneven cable loads or sagging. Adjust as necessary before routing cables . 6. Optional On-Site Adjustments In some cases, the main tray may need to be cut or modified slightly to fit the tee properly, especially when using branch fittings instead of a standard tee . Always follow safety guidelines and manufacturer instructions when making on-site modifications. 7. Cable Routing and Support Once the tee is connected, route the cables according to design specifications, maintaining proper bend radius and spacing. Use cable ties or separators if required to prevent overcrowding and ensure compliance with electrical codes . By following these steps, a multi-cable tray tee can be securely connected, providing a continuous, safe, and structurally sound cable management system.
