The SPIN S1 OPEN pulley , which can be opened even when positioned on the anchor, is designed to simplify the installation of recovery, zip-line, or load diversion systems. Its compact design allows for reduced bulk and weight, particularly during technical rescue. The sealed ball bearing pulley ensures excellent performance. Manoeuvring is made easier thanks to the swivel that allows the pulley to be oriented under load. The opening swivel also ensures the pulley is compatible with a wide variety of products (tripod, REEVE pulley, PAW anchor multiplier, etc.), thus reducing the bulk of the systems used.
