Dmm Revolver

DMM just brought a whole new level of performance to the carabiner. This recent design evolution synergistically combines DMMs masterful deep forging process with a 5.5 mm radius roller to reduce friction in your belay system, rope drag and rope wear. The roller acts like a friction reducing pulley and also eliminates bunching of the sheath and "chatter" when a weighted rope is forced over a carabiner' edge - as in a lead fall.
