DMM Revolver Screwgate Carabiner

The pulley wheel significantly reduces friction when your rope runs through the carabiner. This makes hauling gear or pulling up slack on wandering routes much easier and more efficient.

Yes. The keylock nose creates a smooth, snag-free interface between the gate and the body, which prevents the carabiner from catching on your slings, ropes, or bolt hangers during clipping and unclipping.

While it is designed for technical mountaineering and trad climbing, the screwgate locking mechanism makes it better suited for building anchors, hauling, or complex rigging rather than standard quickdraw use on sport routes.

At 62.37g, it is slightly heavier than a standard non-pulley locking carabiner. However, the added weight is a trade-off for the mechanical advantage provided by the integrated pulley system.

The pulley is designed to accommodate standard climbing ropes. However, it is always best practice to ensure your rope runs freely through the wheel without binding, especially if you are using particularly thick or fuzzy ropes.
