Method for fixing the cover plate in cable trays

Use appropriate cable tray cover clamps or clips to securely fasten the cover, considering tray type, environment, and access frequency.

Choosing the Right Accessory

Cable tray covers can be fixed using no-weld clips, seven-shaped clips, riveting buckles, or specialized cover clamps. The choice depends on:

• Frequency of access: For frequent maintenance, use no-weld clips or rotating buckles, which are easy to remove and reusable .
• Permanent installation: For a more secure hold, riveting buckles or seven-shaped clips clamp the cover firmly to the tray .
• Environmental conditions: In wet or corrosive environments, 304 stainless steel accessories are recommended for corrosion resistance .
• Tray width and type: Wider trays may require stainless steel hoops or multiple clamps to ensure stability .

Installation Methods

1. No-Weld Clip: Snap the clip onto the tray edge; the main body goes inside the tray while a smaller part grips the cover. No tools are needed, making it quick and reusable .
2. Seven-Shaped Clip: Slide the clip onto the tray edge; it locks the cover by clamping both tray and cover. Some models may require a screw for extra security .
3. Riveting Buckle: Provides a permanent hold by mechanically fastening the cover to the tray, ideal for high-vibration areas .
4. PKP-SP Cover Clamps: For perforated or mesh trays, clamps like PKP-SP1, PKP-SP2, and PKP-SPM1 can be screwed or snapped into position depending on the model. These are suitable for demanding conditions such as vertical installations or exposure to wind .

Best Practices

• Secure multiple points: Always fasten the cover at several points along the tray to prevent movement or sagging .
• Check tray alignment: Ensure tray sections are properly aligned and supported to avoid stress on the cover .
• Use corrosion-resistant materials: Stainless steel or galvanized accessories extend the lifespan of the installation, especially in industrial or outdoor settings .
• Inspect periodically: Recheck clips and clamps for loosening, especially in high-vibration or high-traffic areas . By selecting the right accessory and following proper installation techniques, you can securely fix cable tray covers, ensuring safety, accessibility, and long-term durability.
