Black Diamond VaporLock Screwgate Biner

The VaporLock Screwlock Carabiner by Black Diamond is one of the top choices for a belay biner. The VaporLock is the lightest, full function pear locker on the vertical walls. With a smooth increase in friction when used with any belay device, it is ideal for times when you need more control in your device; rappelling or belaying. With a keylock nose and screwlock sleeve, the VaporLock makes it easy to thread through a mass of slings or webbing and lock securely.
