Installation of horizontal wall-mounted cable tray brackets

Horizontal cable tray wall brackets are installed by securely mounting the brackets to the wall, aligning the tray, and ensuring proper support spacing and load capacity.

Tools and Materials Needed

• Wall brackets compatible with your cable tray type (e.g., RVK, TKS, cantilever brackets)
• Drill and appropriate masonry or metal anchors
• Level and measuring tape for alignment
• Screws, bolts, and washers as specified by the manufacturer
• Cable tray sections and couplers
• Safety equipment: gloves, goggles, and hard hat

Step-by-Step Installation

1. Plan the Layout: Determine the tray route, bracket spacing, and load requirements. Refer to local building codes and manufacturer specifications for maximum support spacing and load capacity (typically 3.6 m spacing with 318–340 kg per hanger), .

2. Mark Bracket Positions: Use a level and measuring tape to mark the wall where brackets will be installed. Ensure the tray will be horizontal and aligned with other supports .

3. Mount the Brackets: Drill holes and secure the wall brackets using appropriate anchors or bolts. Brackets should be firmly attached to support the tray and cable weight. For aesthetic installations, some brackets (like RVK) are placed inside the tray for a clean look .

4. Install the Cable Tray: Lift the edge of the tray onto the straight tip of the bracket, then press the other edge into place from below. Ensure the tray sits securely and is level .

5. Connect Tray Sections: Use couplers or connectors to join multiple tray sections. Ensure all joints are tight and aligned to prevent sagging or misalignment .

6. Check Load and Clearance: Verify that the installed tray can support the intended cable load and that there is sufficient clearance for maintenance and other trades .

7. Secure Cables: Once the tray is installed, lay cables and secure them according to electrical codes and manufacturer recommendations. Avoid overloading the tray .

Best Practices

• Use brackets and supports designed for the specific tray type to ensure safety and compliance .
• Maintain consistent spacing and alignment to prevent stress on the tray and cables .
• Avoid using cable trays as walkways or for supporting personnel .
• Consider future expansion and accessibility when planning the layout .

Following these steps ensures a safe, durable, and code-compliant installation of horizontal cable tray wall brackets.
