Petzl Spin L1D

Petzl Spin L1D Very High Efficiency Pulley with One-Way Rotation and Swivel

Openable even when attached to the anchor, the SPIN L1D pulley is designed to be used in conjunction with a descender for maximum simplicity in setting up a deviation for a heavy load. The faceted sheave only rotates in one direction, providing excellent efficiency when hauling and adding friction zones for the rope for additional braking when lowering. The swivel facilitates handling, allowing the pulley to be oriented under load, and direct connection of carabiners, ropes or slings.

Description

• Designed to be used in conjunction with a descender for maximum simplicity when setting up a heavy load deviation or haul systems for work at height or rescue:
  - triple-action opening of the moving side plate is quick and easy, even with gloves
  - the rope can be installed with the device connected to the anchor.
  - red mark provides a visual warning when the moving side plate is unlocked
  - special side plate design protects the rope path and allows the use of a Prusik friction hitch in a progress-capture system
  
• Optimal hauling efficiency and lowering convenience: the faceted sheave only rotates in one direction, providing excellent efficiency when hauling and adding friction zones for the rope for additional braking when lowering heavy loads 
  
• Easy handling:
  - swivel allows pulley to be oriented under load
  - swivel accepts up to three carabiners and allows the use of ropes and slings to facilitate maneuvers.
