Black Diamond

RockLock Twistlock Carabiner

Black Diamond's RockLock Twistlock Carabiner automatically locks after you set the belay for your climbing partner. That means no more looking down and noticing an unlocked gate after you told your partner to climb on. Black Diamond also designed this locker with a keylock nose for snag-free unclipping, a curved spine for a larger gate opening, and a square hinge to hold your belay device in place.
