The SPIN S1 OPEN pulley with a movable side plate, which can be opened even when the pulley is attached to the anchor point, is designed for maximum simplicity when assembling hoists, redirecting rope systems, and tensioning traverses. It is compact, reducing the size and weight of the system, which is particularly useful in technical rescue. The pulley with sealed ball bearings provides excellent efficiency. The swivel allows for easier load manipulation under stress and enables direct connection of slings and carabiners. The separable swivel allows for use with a wide range of other products (tripod, REEVE pulley, PAW anchor plates, etc.), reducing the system size when assembling without the need for carabiners.

Easy to use:

  • Compact pulley designed for maximum simplicity when assembling hoists, redirecting systems, and tensioning traverses
  • Intended for work at height and technical rescue, where weight and size are important factors
  • The three-stage opening system of the movable side plate is quick and easy to operate, even with gloves
  • The rope can be installed even when the pulley is attached to the anchor point
  • A red indicator provides immediate visual confirmation when the side plate is not completely closed and secured
  • The special design of the side plate protects the rope path
Optimal efficiency:



The medium-diameter sheave is mounted on sealed ball bearings for high efficiency



Easy handling thanks to the separable swivel:
  • Thanks to the separable attachment eye with a large opening, the pulley is compatible with a wide range of other products (tripod, REEVE pulley, PAW anchor plate, etc.) and direct connection saves system size – no need for carabiners
  • Allows for pulley orientation under load
  • Ropes or slings can be threaded directly without using carabiners
  • Allows rotation of most carabiners complying with European standards
