How to fix cable tray cover plates

Secure a cable tray cover plate using clips, clamps, or screw-on fasteners depending on tray type and installation conditions.

Step 1: Identify the Tray Type

Determine whether your cable tray is perforated, mesh, or solid-bottom, as the fixing method may vary. Perforated trays often allow for screw-on clamps, while mesh trays may require specialized clamps or clips for stability .

Step 2: Choose the Appropriate Fixing Method

• Snap-on Clips: Quick to install without tools, ideal for areas where covers may need frequent removal. The clip snaps onto the tray edge, holding the cover securely with pressure. Typically made of 304 stainless steel for corrosion resistance .
• Screw-on Clamps: Provide a more permanent hold, suitable for high-vibration or outdoor environments. Examples include PKP-SP1 and PKP-SPM1 clamps, which are screwed into position on perforated or mesh trays .
• Turn Buckles or Joint Plates: Some covers come with pre-mounted turn buckles or require joint plates to secure the cover. These are fastened with bolts and nuts, ensuring the cover remains aligned and stable .

Step 3: Installation Procedure

1. Align the Cover: Place the cover over the tray, ensuring it fits flush with the edges.
2. Attach Clips or Clamps:
   • For snap-on clips, press the clip into place so it grips both the tray and cover.
   • For screw-on clamps, insert screws through the tray rail from the inside and secure with nuts on the outside to avoid cable damage .
3. Check Stability: Ensure the cover does not move or sag. Adjust or add additional clips/clamps if necessary.
4. Edge Protection: If the tray has cut edges, attach an edge protection strip to prevent cable damage .

Step 4: Maintenance Considerations

• Reusable Clips: Snap-on clips can be removed and reused for maintenance access .
• Regular Inspection: Periodically check clamps and screws for loosening, especially in high-vibration areas .
• Load Compliance: Ensure the tray and cover are not overloaded, as excessive weight can cause sagging or joint failure . By following these steps and selecting the correct fixing accessories, you can ensure your cable tray cover plate is secure, safe, and compliant with installation standards.
