Whichever way you look at it, this is a remarkable biner design. If you don’t already own some Revolvers we would urge you to give it some serious consideration, and here’s why:

• The pulley wheel is a unique design feature that solves the age-old problem of rope drag.
• It also makes this biner a very useful tool in rescue or emergency hauling situations when a pulley is required.
• The wire gate version of the Revolver is a well established, design classic and many climbers have wisely added them to their racks.
• But if you want extra security, say for example when clipping crucial runners or in an emergency pulley system, the locking version of the DMM revolver is the better option.
