DMM Revolver Locking Carabiner

The pulley wheel replaces the standard fixed surface of a carabiner spine with a rotating wheel. This significantly reduces friction when your rope runs over the carabiner, making it much easier to pull slack or haul loads during complex rigging.

Yes, it can be used for lead climbing, particularly on wandering routes where rope drag is a major issue. However, because it is slightly heavier and more complex than a standard carabiner, most climbers prefer to reserve it for specific placements where friction management is critical.

No. The carabiner features a keylock nose design, which creates a smooth, snag-free interface. This ensures that the gate won't catch on your rope, slings, or harness loops when you are clipping or unclipping.

Not at all. Despite the inclusion of the pulley wheel, the Revolver maintains a robust major axis strength of 24kN. It is built with hot-forged I-Beam construction, which provides high structural integrity while keeping the overall weight manageable.

Absolutely. The Revolver is an excellent tool for creating 3:1 or 5:1 hauling systems. The integrated pulley increases the efficiency of your system by reducing the energy lost to friction, making it a staple for self-rescue and crevasse rescue kits.

While it looks good, the primary purpose of the anodized finish is to provide essential corrosion resistance. This helps protect the aluminum from the elements, extending the lifespan of the carabiner when used in damp or harsh outdoor environments.
