Black Diamond Climbing carabiner Rocklock

The Black Diamond RockLock carabiner, our largest belay and abseiling carabiner, features a safety spout, is compatible with a half-cabestan knot and can be handled with one hand. Léger and now hot-forged, with a redesigned edge for better grip and a larger rope working surface for greater strength, the RockLock is the essential safety carabiner for daily climbing season after season.
