The Mammut Smart HMS 2.0 Screwgate Carabiner offers the same double safety and easy handling as the older version. The screw locking can beĀ operated only when the safety gate is open. Accidental opening is excluded, as well as unintentional twisting of the carabiner in the belay loop of the climbing harness. This prevents dangerous lateral loading. Mammut recommends use of the Smart HMS 2.0 carabiner for the Smart 2.0 belay device.
