Cut the cable tray T-junction

A T-junction in a cable tray can be created on-site by marking the cut, using appropriate cutting tools, and securing the branch with connectors or bolts while protecting the cut edges.

Step-by-Step Process

1. Plan and Mark the Cut Measure the location where the branch will connect to the main tray. Mark the outline of the T-junction on the main tray, ensuring the branch aligns at a 90-degree angle or the desired orientation. Accurate marking is crucial for a clean fit and proper alignment with the branch tray . 2. Select the Right Tools For wire mesh cable trays, a bolt cutter is commonly used to cut the tray live on-site. For solid or ladder-type trays, a hacksaw, angle grinder, or metal shears may be required. Ensure the tool is suitable for the tray material and thickness . 3. Make the Cut Carefully cut along the marked lines. For wire mesh trays, the bolt cutter will drag a layer of zinc across the cut, forming a protective layer. For solid trays, smooth the edges with a file or deburring tool to prevent injury and protect cables . 4. Protect the Cut Edges Use rubber caps or edge protectors to cover sharp edges, especially in wire mesh trays, to prevent damage to cables and ensure safety during installation . 5. Attach the Branch Tray Position the branch tray into the cut T-junction. Secure it using tray connectors, bolts, or clamps as recommended by the manufacturer. Ensure all connections are tight and the trays are level . 6. Verify Alignment and Stability Check that the T-junction is properly aligned and stable. Adjust as necessary before running cables through the tray. Proper alignment ensures smooth cable routing and prevents stress on the tray or cables .

Additional Tips

• Always wear safety gloves and eye protection when cutting metal trays.
• For complex installations, consider pre-fabricated T-junction fittings if available, which can save time and improve structural integrity .
• Follow the manufacturer's installation guide for specific tray types, as cutting methods and protective measures may vary . By following these steps, you can safely and efficiently create a T-junction in a cable tray system while maintaining structural integrity and cable protection.
