SPIN S1 Open

The SPIN S1 Open is a compact and highly efficient single pulley with a lockable swivel, perfect for rigging and rescue situations. Its openable side plate makes it easy to use even when attached to an anchor point.

The SPIN S1 Open from Petzl is designed for maximum ease of use when setting up hauling systems, load deviations, and tensioned highlines in work at height and technical rescue, where weight and size are crucial factors. Its compact design minimizes weight and bulk, which is particularly valuable during demanding operations. The sealed ball bearing sheave provides exceptional efficiency at 91%. The integrated swivel facilitates handling by allowing rotation under load and direct connection of carabiners, ropes, or slings. The openable gate on the swivel makes it compatible with a wide range of equipment such as tripods, REEVE pulleys, and PAW rigging plates, reducing bulk during installation.
