The Nimbus HMS Lock Carabiner\'s unique rounded design positions ropes perfectly for rappels and creates a very wide gate opening with substantial inner working space. Unlike many belay carabiners, the HMS Compact has no corners so ropes have nowhere to bunch, resulting in less friction for smoother rappels and belays and helps keep heat to a minimum on long rappels.Compact HMS belay and rappel carabiner with secure screw lock closureNew screw gate is lightweight and easy to handleProprietary SphereLock nose makes clipping ropes and webbing easyLaser etched marking to indicate if the lock is open or closeLength: 101mmWidth: 71mmGate Opening: 22mMajor Axis (kN): 21Minor Axis (kN): 9Open Gate (kN): 6
