Black Diamond Locking 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 the twist-lock sleeve can be manipulated 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 must-have safety carabiner for daily climbing season after season.
