Dmm Revolver Carabiner -
A small pulley in the basket end the DMM Revolver Carabiner reduces friction as your rope runs through it. This means that you won't feel like you're dragging a tug boat line as you're making the last few moves on your rope-stretching project. The Revolver Carabiner can also be used for light hauling and rescues, making it a versatile addition to any climber's rack.


  • Extremely strong and light Hot Forged I beam construction.


  • Roller action and size dramatically extends rope life.


  • Reduces rope drag significantly.
  • Meets CE standard EN 12275 for carabiners as well as EN 12278 for pulleys.
  • Innovative lightweight rescue, hauling and rigging applications.
  • Weight 1.5oz (44g).
  • Large rolling rope redius 5.5 rad (11mm dia).

The Revolver reduces rope drag significantly. This is particularly noticable on long pitches and pitches that include changes in angle or direction. The Revolver simplifies the setting up of a pulley/haul systems on both land and water. The Revolver helps dissipate the energy generated in a fall. over a greater proportion of the rope and reduces the force to the top anchor. The Revolver reduces the force felt by a lead climber in a fall. Location groove protects and locates 12 mm dyneema express sling. The first carabiner designed specifically to reduce friction. The Aluminum roller will keep rolling up to 11.5kN so that the forces generated on the anchor in a fall will be reduced. The pulley was built to EN 12278 Standards The roller sits on a self lubricating polymer bearing. The roller and bearing sit on a stainless steel spindle and spindle sleeve.

With this staggering fact in mind, DMM has abandoned convention, thrown away the rule book and approached the energy issue from a completely new angle knowing that weight is the enemy of the climber. The weight of a rope and friction that occurs in use make it the crucial issue. We believe we have redefined the carabiner by introducing the concept of a rolling component in the safety chain. Designed for use at rope clipping end of a quickdraw, this extremely light and strong biner works mechanically in your favor. What more can you ask?

This biner really does reduce friction on wandering pitches and I've used it far more than I ever expected to. Now that it's available in a locker, it's also a nice addition to a glacier kit as an emergency pulley. That being said, if you're really planning to use a pulley, you'd best stick with a dedicated device.

Awesome piece of Pro

I climb mainly in Red River Gorge. Stick clipping the first bolt is common practice and I use one particular draw and noticed significant wear on that biner due the sand. This eliminates the potential of a ginsu knife edge developing...

I have used these for crevasse rescue and they lower the resistance quite a bit when pulling using the Z / C systems. I think I read where they can reduce resistance 25-40 % vs. standard carabiners in that capacity.

I don't care for the product name.

I'm not a climber, but I use climbing equipment to fly very large kites. The top roller will be very helpful when putting up and taking down the kites.
