The DMM Revolver Kwiklock features an integrated pulley wheel that allows ropes to move more efficiently through the carabiner. It is used for directional changes along a route, helping to reduce rope friction.

The Revolver is also particularly useful for creating lightweight lifting systems. If you need to haul up gear, a partner, or perform a rescue from a gorge, the pulley wheel increases efficiency and converts more of your energy into movement.

A closed gate provides additional safety for the Revolver.
