DMM Revolver Screw Lock Carabiner


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 and converting more of your energy into movement.

A locking gate gives the Revolver extra security.


  • Keylock nose creates a clean internal profile that won’t catch on gear, bolts or slings, giving easier clipping and removal from systems.
  • I-Beam construction for optimum strength to weight ratio. This is achieved through hot forging, a process which allows metal to be made into complex shapes that improve functionality.
  • The Revolver’s pulley wheel reduces friction and increases the efficiency of ropes running over it. This reduces rope drag on complex pitches, and rope wear when used as an anchor for top roping.
  • The Revolver can also be used to create a mechanical advantage in a lightweight personal hauling system, making it indispensable as part of a climber’s personal rescue kit. The pulley wheel is functional with loads up to 11kN.
