The Black Diamond Rocklock Twistlock carabiner is one of Black Diamond's largest locking biners. The new Keylock has a non-snagging keylock nose. A slightly curved spine maximizes the gate opening and a square hinge end holds your belay loop securely in place. The Rocklock's large size makes it an excellent choice when using two ropes, wearing gloves, or when using a variety of belaying and rapelling techniques. Its large capacity can handle multiple clove hitches at belays. The Rocklock Caribiner is easily operated with one hand.
