The Petzl SPIN S1 compact pulley with swivel is designed for high-efficiency hauling, load deviation, and tensioned highline systems in work-at-height and technical rescue applications. Compact and lightweight, it minimizes bulk while delivering excellent mechanical performance. The opening side plate allows the rope to be installed while the pulley remains connected to the anchor, simplifying rigging operations. A sealed ball bearing sheave ensures smooth rotation, while the integrated swivel supports optimal orientation under load.
