DMM Revolver


Reduce rope drag on winding pitches with a carabiner with an integrated pulley


“What’s the heaviest thing on your rack? Answer: your rope!”

The frictional drag that a rope can exert on you, particularly on a long and winding pitch, can be so strong as to actually make upward progress almost impossible. Sure, if you’ve had the foresight to extend that crucial runner below the roof with a long sling, you’re halfway there, but once you’re trucking up the final headwall, forearms dangerously pumped, and a few more runners placed here and there as the line of the route twists about, it feels like you’re dragging an elephant behind you.

The answer to the epic rope drag scenario was to look at the hardware end of the system. The Revolver has an in situ pulley roller fitted into the apex of a biner. A simple, but extremely effective solution to an age old problem. In practice, a Revolver placed at changes of direction on a long pitch can prevent that heavy harness feeling.

The Revolver also has a further interesting function – it can be used in rescue situations as a pulley. And for added security, there are locking versions available.

We’re not suggesting that you should climb exclusively on Revolver quickdraws, far from it, but it does make sense to have at least a couple on your rack.
