The Black Diamond Rock Lock 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 Rock Lock is the must-have safety carabiner for daily climbing season after season.
