Swing side self-blocking pulley.
The self-locking pulley is designed for rescue operations. 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 2-3/8" (60 mm) diameter aluminum pulley is mounted on self-lubricating bushing and stainless steel axle. The swing sides are also made of anodized aluminum.
