Climb safer and smarter with the Black Diamond Rocklock carabiner. The keylock nose prevents rope snagging, while the unique gate design utilizes two magnetic arms and a steel inset for maximum security and simple closure. Requiring only one hand to operate, you can keep three points of contact for a safer climb. With a square hinge end, the Rocklock helps keep your belay rope in place, and the gently curved spine allows for optimal gate opening.
