Petzl SPIN L1D One-Way Rotation Pulley

Openable even when attached to the anchor, the Petzl 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.

• 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.
• 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 pulley enables setting up a deviation for a heavy load, in conjunction with a descender.
