The pulley at the bottom of the main lock solves the problem of friction during rope dragging. Especially when climbing on rock walls or rescuing from cracks, it can serve as both a pulley and a lock, reducing the frictional resistance between the rope and the lock, making the operation more convenient and effortless.
