Absolutely. As an HMS-style carabiner, the RockLock is shaped specifically to accommodate Munter hitches and is compatible with most standard belay devices.

The square hinge end is designed to keep your belay loop securely positioned at the bottom of the carabiner. This prevents the carabiner from rotating, which helps keep your belay system organized and safe.

Hot-forging allows for a more precise distribution of material, meaning the carabiner is stronger where it needs to be and lighter where it doesn't. It results in a durable, high-strength tool that doesn't add unnecessary weight to your rack.
