Answer: pulling grips and Swivels are essential tools that work together to protect the integrity of fiber optic cables during the pulling process.

• pulling grips: Also known as cable socks or stockings, these are woven mesh devices that securely attach the pulling rope to the cable. Their design ensures that the pulling force is applied to the cable's strength members, not the delicate internal fibers, preventing strain and elongation. The grip's strength increases as the tension on the pulling line increases, providing a reliable hold.

• Swivels: A swivel is a vital anti-twist device that connects the pulling grip to the winch's pulling rope. It allows the pulling rope to rotate freely without transferring that rotation to the cable. This prevents the cable from twisting, kinking, or coiling, which could cause permanent damage to the fibers.
