The Black Diamond Rocklock Twistlock Carabiner is the largest belay and rappel locker that Black Diamond produces. The square hinge end holds the belay loop firmly in place while the keylock nose prevents snagging. The oversize design on this Black Diamond carabiner ensures it is Munter Hitch compatible for added friction in a belay or rappel situation and it is operable with one hand for increased ease of use. If you're putting together a belay system for the gym or the crag, the versatility of the Rocklock Twistlock Carabiner makes it a great choice for either.
