Answer: Using the correct Swivel and grip is paramount to a successful and damage-free installation. Fiber optic cables should never be pulled directly by their outer jacket. Instead, the pulling force must be applied to the cable's internal strength members (like Kevlar aramid yarn or fiberglass rods). A purpose-built pulling grip, used in conjunction with a Swivel, ensures the pulling load is distributed evenly to these strength members. This combination of a specialized grip and swivel prevents twists, maintains the cable's integrity, and ensures the installation adheres to the manufacturer's specified pulling tension and bend radius limits.
