PKPSP Series Clamps Enhance Secure Cable Tray Covers

Safety concerns regarding cable tray covers in harsh conditions—such as high winds or vertical installations—have long troubled engineers and technicians. Loose covers not only compromise aesthetics but pose significant safety risks. The PKP-SP series of clamps offers a reliable solution to these challenges.

In electrical and communication infrastructure projects, cable trays serve a critical role by supporting and protecting cables from mechanical damage and environmental factors. However, certain conditions present unique challenges:

• Vertical installations in high-rise buildings increase the risk of cover detachment due to gravity
• Coastal areas or high-wind zones may experience covers being blown open
• Industrial environments with heavy vibration can cause cover loosening

Standard snap-on mechanisms often prove insufficient in these scenarios, necessitating additional mechanical fastening solutions.

The PKP-SP clamp series addresses these challenges through specialized designs that provide secure mechanical fixation. Three distinct models accommodate various cable tray types:

Designed specifically for perforated cable trays, the PKP-SP1 requires tool-assisted installation:

1. Position the cover correctly on the tray
2. Align the clamp with tray perforations and cover edge
3. Secure with a screwdriver, avoiding overtightening

Also for perforated trays, the PKP-SP2 features a tool-free design:

• Align clamp with tray holes and cover edge
• Press firmly to secure
• Remove with simple tools when needed

Tailored for grid-type trays, the PKP-SPM1 follows similar installation to PKP-SP1 but with grid-specific engagement:

1. Position cover on grid tray
2. Align clamp with grid structure and cover edge
3. Secure with screwdriver, maintaining proper torque

Proper clamp selection based on tray type and environmental conditions ensures optimal cable management system performance. The PKP-SP series offers versatile solutions ranging from tool-dependent to tool-free options, all designed to maintain cover integrity under demanding operational conditions.
