The double self-locking pulley was especially designed for rescue operations. However, it most certainly can be used in forestry, hunting our industrial applications as well. It features two sheaves and a brake cam system which allows the rope to go through freely in one direction and blocks it in the other direction. The spring-loaded cam can be disengaged by pulling a release cord. The 62 mm diameter aluminum sheaves are mounted on self-lubricating bushings and stainless steel axle. The swing sides and main plate are also made of anodized aluminum.
This pulley can also be used as a regular double pulley. You simply have to lock the brake cam in the open position using the provided pin.
Use one of our carabiners (PCA-1701 or PCA-1702) to attach it.
Ideal rope diameter: 12 mm.
