Black Diamond Rocklock Screwgate Carabiner - The Black Diamond RockLock is Black Diamond's largest locking belay/rappel carabiner. It has a keylock nose, is suitable for use with the half mast hitch and can be operated with one hand. It owes its now lower weight to the hot-forged construction, while its revised back ensures better handling and the large rope contact area makes the RockLock a durable companion for years of use.
