Mesh Cable Tray Installation Tutorial

Mesh cable trays can be installed efficiently by following proper cutting, joining, bending, and mounting procedures using compatible accessories and supports.

Preparation and Planning

Before installation, plan the cable tray route considering cable types, load, and environmental conditions. Ensure the selected mesh tray type supports the intended cables and complies with temperature and corrosion requirements (e.g., -20°C to +120°C for OBO CMS trays) . Measure and mark the tray path, including bends, tees, and level changes.

Cutting and Handling

Mesh trays can be cut to length using a power cutter or hacksaw. Always wear protective gloves and eye protection, as cut edges can be sharp . For bends or custom shapes, the mesh can be manipulated on-site without pre-purchased bends, allowing flexibility in installation .

Joining Sections

• Use connectors or snap-in systems to join straight sections. For example, Cablofil trays use a PRECLICK system where each tray section snaps together with a screwdriver or light tap .
• Ensure the correct number of nuts, bolts, or fasteners are used to secure joints and maintain structural integrity .

Creating Bends and Tees

• Mesh trays allow on-site fabrication of 90° bends, tees, and radius curves.
• Bend the tray carefully to avoid deforming the mesh and maintain cable support. Use specific accessories if required for fast and secure connections .

Mounting and Supports

• Install trays using wall brackets, ceiling hangers, or floor supports depending on the layout.
• Maintain proper spacing between supports to prevent sagging; spacing depends on tray type and cable load.
• Ensure trays are level and aligned along the planned route .

Cable Installation

• Feed cables into the tray, taking advantage of the open mesh design for ventilation and easy access.
• Separate power and data cables if required, and avoid overloading the tray beyond its rated capacity .

Safety and Best Practices

• Always follow manufacturer guidelines for load capacity, environmental conditions, and accessory usage.
• Handle trays carefully to avoid injury from sharp edges.
• Verify all connections and supports are secure before running cables . By following these steps, mesh cable trays can be installed efficiently, safely, and with flexibility for future modifications or expansions.
