DMM Revolver Screwgate

The Revolver Screwgate, what does it do? In simple terms the carabiner uses rolling friction rather than the sliding friction of the rope over the bar typified by a standard carabiner. In this case the rope rolls over the pulley wheel which means much less friction is created. Less friction means less force holding the climber back, which makes upward progress a lot easier. Other important factors to consider are that since the rope rolls over the roller, there will be less wear and tear on your rope. Also, by reducing the friction the forces involved when a climber falls are more evenly distributed throughout the system, resulting in less force being inflicted on the last piece of protection placed. The Revolver is NOT recommended for frequent use lowering situations. Specifications: Weight: 64g. Strength (gate closed): 24 kN. Strength (gate open): 8kN. Strength (minor axis): 8kN.
