Connecting Mesh Cable Trays and Cable Trays

Mesh cable trays are connected using couplers, bolts, clips, or proprietary splice kits to ensure secure, aligned, and continuous cable support.

Step-by-Step Connection Process

1. Plan and Align the Trays Before connecting, ensure the trays are properly aligned along the intended cable pathway. Misalignment can cause uneven loads, sagging, or stress on the cables, so use a level and measuring tools to confirm alignment . 2. Select the Appropriate Connection Method

• Couplers or Splice Kits: These are commonly used to join two tray sections. They provide a rigid, secure connection and are often designed specifically for the tray manufacturer .
• Bolts and Fasteners: For heavier cable loads, bolt sets offer a more rigid connection. Position the tray ends together and secure with bolts through pre-drilled holes .
• Clip Systems: Some mesh trays allow tool-less clip connections for quick installation, ideal for speed-sensitive projects . 3. Secure the Connection
• Place the ends of the trays together, ensuring the mesh grids interlock or align with the coupler.
• Tighten bolts or clips evenly to maintain structural integrity. Avoid over-tightening, which can deform the mesh .
• Check that the trays are level and continuous to prevent cable stress. 4. Grounding and Bonding For metallic mesh trays, ensure electrical continuity across the connected sections. Use bonding jumpers at splice points if mechanical connections alone do not guarantee conductivity. Proper grounding protects personnel and equipment from fault currents and ensures NEC compliance . 5. Final Inspection
• Verify that all fasteners are secure and the trays are aligned.
• Test the system by running a small cable load to confirm stability.
• Inspect for any gaps or misalignment that could compromise cable support .

Tips for a Professional Installation

• Use manufacturer-recommended splice kits for faster, compliant installation.
• Avoid overloading trays; distribute cable weight evenly.
• Regularly inspect connections for wear, corrosion, or loosening over time . By following these steps, mesh cable trays can be securely connected to other trays, ensuring a safe, durable, and efficient cable management system.
