Petzl® Swivel Open is a gated swivel with sealed ball bearings and large opening for attachment to a wide range of products including pulleys, lanyards and more. It reduces the bulk and weight of component systems and solves twisting and tangling problems with ropes and lanyards in different situations – Hauling: prevents rope twist when the load turns on itself, thus reducing kinking. Avoids the risk of friction between ropes, which improves efficiency. Progression with Lanyard: avoids twisting and simplifies manipulations. Sealed ball bearings offer excellent performance and reliability.
