The lightest, full-function pear locker on the planet, the new VaporLock provides a smooth increase in friction when used with any of our ATC devices. The VaporLock is ideal for those times belaying and rappelling when you want more control. On ropes up to 9.4 mm, the VaporLock is Munter Hitch compatible. A keylock nose and screwlock sleeve make it easy to thread through a rat's nest of slings and lock securely.
