DMM Revolver Carabiner

The pulley wheel replaces the standard metal surface of a carabiner with a rotating wheel. This significantly reduces friction as the rope moves over it, allowing the rope to glide smoothly rather than dragging against the metal, which makes clipping and movement feel much lighter.

It is excellent for lead climbing, especially on routes with complex zig-zags or sharp edges where rope drag becomes a major issue. You can use it as a standard quickdraw carabiner, but it really shines when placed at the specific points where the rope creates the most friction.

Yes, it is a fantastic tool for those applications. The pulley wheel makes building mechanical advantage systems much more efficient, as it converts more of your physical effort into actual movement of the load compared to a standard carabiner.

Not at all. The wiregate is a proven, reliable design that is less prone to freezing in cold conditions and lighter than solid gate alternatives. It maintains the same high safety standards you expect from DMM gear.

While it is slightly heavier than a standard, non-pulley carabiner due to the integrated wheel, the trade-off is often worth it. By reducing rope drag, you save energy over the course of a long pitch, which is usually more valuable than saving a few grams on your rack.
