The focus is on safety with the Mammut Element Smart HMS Carabiner. The twistlock can only be operated when the safety gate is open, preventing the accidental opening of the carabiner as well as twisting in the belay loop of the climbing harness. This avoids disadvantageous loads on the minor axis of the carabiner.
