The swivel facilitates operations, allowing the pulley to be oriented under load and direct connection of carabiners, ropes, or slings. The system is prebuilt with 200 ft / 61m of 11mm Petzl Axis rope with sewn end terminations; therefore, no knots are required, and the rope can easily be replaced over time.
