DMM Revolver Locksafe Aliminium Karabiner

DMM Revolver Carabiner

The DMM Revolver Carabiner brings a completely new take on the way carabiners work as it uses rolling friction rather than sliding friction as in a normal karabiner when the rope runs over the carabiner bar.

With the DMM Revolver Carabiner, the rope rolls over the pulley wheel which means much less friction is created. Less friction means less force holding the climber back which makes upward progress a lot easier.

The benefits of the DMM Revolver Carabiner are obvious when a number of runners have been placed on a longer route and even more apparent when sudden changes of direction are encountered, such as when the route traverses or goes over a bulge. It's at these placements where most benefit will be experienced in terms of reducing friction.

Other benefits of the DMM Revolver Carabiner include there being less wear and tear on the rope due to the rope rolling over the roller, which will considerably increase the rope's working life. Also, by reducing the friction the forces involved when a climber falls are more evenly distributed throughout the system, resulting in less force being inflicted on the last piece of protection placed. If this last piece is marginal, it could be a very real benefit.

The DMM Revolver Carabiner also offers options in terms of rigging hauling systems or improvised rescue, as it works just like a small pulley, making the DMM Revolver Carabiner a very versatile piece of kit.

The roller itself is made of 7075 and blends smoothly into the back of the carabiner to encourage the rope to run correctly. Inside the roller is a dry tube Igus bearing which in turn is supported by a high tensile stainless sleeve over a high tensile stainless spindle. The whole assembly runs very smoothly and the sealed bearing tubes as it wears. It is also very strong, and the spindle will not deform until a force approaching 10 to 12 kN is generated.

Carry two or three in your kit and use them as suggested above, enjoy the benefits of less friction, less rope drag, and be comforted by the fact that you are also carrying a couple of pullies with you for emergencies. The DMM Revolver carabiner (Locksafe) is fully certified as both a carabiner and pulley. This makes the DMM Revolver Carabiner ideal for use in hauling or rescue systems where complete safety and legislative compliance is required.
