Side-wall cable tray fixing

Cable trays can be securely fixed to side walls using compatible brackets, supports, or hangers designed for the tray type and load requirements.

Wall-Mounting Methods

1. Brackets and Supports: Cable trays are typically mounted to walls using wall brackets or supports that attach to the tray's side walls. These supports can be adjustable to maintain a gap between the tray and the wall, usually ranging from 0–40 mm, allowing for proper cable bending and airflow . Brackets may be placed inside or outside the tray depending on aesthetic or structural requirements . 2. Edge Engagement: During installation, the edge of the cable tray is lifted onto the bracket tip, and the opposite edge is pressed into place from below to ensure a secure fit . This method provides a clean and stable installation, especially in visible areas where design matters. 3. Compatible Fixings: Specialized fixings, such as Gripple cable tray hooks, are compatible with all side wall holes and slots, regardless of size. These systems can support trays from 100 mm to 300 mm wide and handle loads up to 45 kg with a 5:1 safety factor . Stainless steel hangers and adjustable wire rope systems are suitable for extreme environments or architectural applications.

Best Practices

• Follow Standards: Ensure trays and supports comply with BS EN 61537 for cable trays and ladders .
• Load Considerations: Select supports that can handle the weight of the cables and any additional equipment.
• Spacing: Maintain proper spacing between brackets to prevent sagging and allow for cable expansion.
• Cable Management: Avoid using trays as walkways or for supporting personnel; they are designed solely for cable support .
• Custom Fit: Flexible trays like the Wall Snake can be bent to match wall contours, ensuring proper cable bending radii .

Tools and Materials

• Wall anchors or screws compatible with the wall type
• Adjustable brackets or RVK-type supports for KR-type trays
• Level and measuring tools to ensure alignment
• Optional: wire rope hangers or stainless steel hooks for heavy-duty or aesthetic installations By following these methods and using compatible supports, cable trays can be safely and securely fixed to side walls, ensuring both functional and visually appealing installations.
