Wire Rope Clamping Wedge ZLK-4 No name – steel wire rope clamp ZLK-4

Wedge-style wire rope clamp ZLK-4 by No name is a compact steel clamp designed to secure and terminate steel wire ropes without deforming the main line. The wedge mechanism grips the rope by pressing a tapered insert into the clamp body, producing a secure hold that can be used for temporary or long-term connections. Its small footprint and removable design make it suitable for rigging, lifting slings, guying, and other applications where a reliable, non-destructive termination is required.

Advantages

The ZLK-4 clamp provides secure gripping through a wedge action that avoids crushing the main rope, preserving rope strength and flexibility. Constructed of steel, it offers durability and resistance to mechanical wear in standard environments. Its removable wedge design allows for quick installation, adjustment or replacement without cutting the rope, which simplifies field operations and reduces downtime.

Suitable for

• Temporary or adjustable terminations of steel wire rope
• Rigging and sling assemblies where compact clamps are needed
• Guying and anchoring of poles or masts
• Load securing during transport and construction tasks
• Field repairs and test setups that require non-permanent connections

Key specifications

• Design: wedge-style clamp for steel wire rope
• Material: steel construction for mechanical strength
• Function: grips rope without deforming primary line
• Application: suitable for temporary or permanent terminations
• Form factor: compact and removable wedge insert

How to use

Insert the free end of the steel wire rope into the clamp body according to the rope path, then drive the tapered wedge into position so it seats firmly against the rope. Apply the recommended tightening method for the clamp design until the wedge holds the rope securely. Verify the connection by applying a controlled load or inspection pull to ensure the wedge is properly seated and the rope is held without slipping. For critical lifting or rated applications, follow applicable standards and procedures for making and inspecting terminations.

Usage recommendations

Use the ZLK-4 clamp with ropes within the clamp’s compatible diameter range and inspect the clamp and rope regularly for wear, corrosion, or deformation. Avoid using a single clamp for overhead lifting of personnel unless specifically certified for that use; for rated lifting, use certified terminations and multiple clamps as required by standards. Store clamps dry and clean when not in use to prolong service life.
