The DMM Revolver carabiner is an amazingly functioning piece of kit in rescue situations, wandering routes, roofs, bulges or when run out on a marginal gear placement. At the crag or in the mountains a couple of these DMM Revolvers could save you from a world of pain.

Because the pulley wheel is built into the carabiner, it also means that you don't have to cart extra bulk and weight up the cliff that you wouldn't be taking anyway. Hence as a rescue set-up it is a really lightweight way to go about it either for multi-pitch climbs or mountaineering. 



  • Extremely strong and light Hot Forged I beam construction
  • 10 mm diameter roller, action and size dramatically extends rope life, rolling friction rather than sliding friction
  • Aids even distribution of forces over the system during a fall
  • Wire gate curved for constant tension, pulls into the nose under load
  • Use as part of a climbing, rescue, hauling or rigging system

Materials:  7000 alloy, anodised, hot forged
Major axis:  24 kN
Gate open:  9 kN
 Minor axis:  7kN
 Gate opening:  24 mm

  • What is the efficiency of the pulley?


    So DMM don't provide an efficiency rating for the Revolver carabiner and I don't think they even test it for this. My first response is to suggest that if you are looking at efficiency ratings of pulleys then the revolver is not the product for you. Remember it has no bearings in it so it probably won't compare well to a proper bearing pulley. Think of it maybe more as a carabiner with extremely reduced drag, and as a backup pulley simillar to the PETZL Nylon Pulley wheel - great as an emergancy pulley at a squeeze but not so much if you are purposely setting up a rigging system. 

    Saying this though I have reached out directly to DMM to see if they have any stats on it. I'll post the results here if I here anything useful back. 

    Many thanks,
