Cable tray fixing clip U-shape

U-shaped clips are used to secure cables in trays or trunking systems by first fixing the clip to a surface or tray, then folding the tabs over the cables to hold them in place.

Types of U-Shaped Clips

• Metal U-Clips: Made from steel or corrosion-resistant materials, suitable for heavy-duty cable trays and high-temperature environments .
• Plastic U-Clips: Lightweight and ideal for non-metallic trunking or surface mounting, often used for smaller cable bundles .
• Fire-Rated U-Clips: Designed to withstand high temperatures (>1200ºC), suitable for fire performance cables and certified for safety .

Installation Steps

1. First Fix the Clip: Attach the U-shaped clip to the cable tray, trunking base, or directly to the surface using screws, shot-fired nails, or fire-rated fixings depending on the clip type .
2. Insert the Cables: Lay the cables into the U-shaped clip, ensuring they are properly aligned and not twisted.
3. Secure the Cables: Fold the clip's tabs inward to hold the cables firmly in place. This prevents movement and maintains organization .
4. Spacing and Support: Ensure clips are spaced according to cable weight and tray specifications. For wire mesh trays, supports are typically required every 8 feet to prevent sagging .

Considerations

• Tray Width Compatibility: Choose clips that match the tray or trunking width (e.g., 25mm, 30mm, 40mm, 50mm) to ensure a secure fit .
• Material Selection: Use corrosion-resistant or fire-rated clips for environments with high humidity, heat, or fire safety requirements .
• Accessibility: Clips allow easy addition or removal of cables without dismantling the tray system . Using U-shaped clips correctly ensures organized, secure, and safe cable installations, maintaining both mechanical stability and compliance with fire and electrical safety standards.
