Single Swing Side Self-blocking Aluminum Pulley

This Self-locking Pulley ensures that your load is secured when pulling up an embankment or hill. It features 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 2-1/2" diameter aluminum pulley is mounted on self-lubricating bushing and stainless steel axle. The swing sides are also made of anodized aluminum. The block can also be pinned out of position and this can be used as a regular 2-way pulley if the application calls for it.
