Professional Answer: The working principle of a cable grip, also called a wire mesh pulling grip or cable stocking, is both simple and ingenious. The grip is a flexible, woven mesh tube that is slipped over the end of a cable. When pulling tension is applied, the woven mesh naturally tightens and constricts around the cable's jacket. The harder you pull, the tighter the grip becomes. This design effectively distributes the pulling force evenly across the surface of the cable, preventing damage and ensuring a safe, reliable pull.
