The DMM Revolver's pulley wheel reduces friction on ropes moving through the carabiner. Placed where the pitch changes direction, it reduces rope drag and makes upward movement easier.
The Revolver can be used in an improvised hauling system to help your second over a crux, haul kit bags, or rescue your partner from a crevasse. Where normal carabiners in these systems cause energy to be lost as friction, the Revolver's pulley wheel makes hauling easier by converting more of your energy into movement.
Integrated pulley wheel for reducing friction
The pulley wheel reduces friction and increases movement efficiency. It can combat rope drag on complex pitches, and decrease rope wear when used as an anchor point when top roping. The Revolver can also create mechanical advantage in a lightweight hauling system, making it indispensable as part of a climber’s personal rescue kit. The pulley wheel is functional with loads up to 11kN.
Wire gate for maximum weight saving
Wire gates are the lightest gate type available, and resist freezing shut in cold conditions. They help reduce rack weight, and are ideal for trad, winter, and alpine climbing.
Small gate notch reduces snagging
Wire gate carabiners require a gate notch to achieve their full strength rating. DMM notches are minimised while remaining functional, to reduce snagging on other equipment.
I-Beam construction for optimum strength to weight ratio
I-Beam construction reduces carabiner weight without compromising strength. It is achieved through hot forging, which allows metal to be formed in complex shapes that improve functionality.
