The Revolver's integrated pulley wheel allows ropes to run more efficiently through the carabiner. Used at changes of direction on a route, it helps reduce rope drag.
The Revolver is also highly useful for creating lightweight hauling systems. If you need to haul kit, a partner, or perform crevasse rescue, the pulley wheel increases the efficiency & converting more of your energy into movement.
A locking gate gives the Revolver extra security.
