Featuring Black Diamond’s new magnetic locking mechanism, the Magnetron GridLock carabiner brings a new level of ease and safety to belay-specific carabiners. This unique gate design doesn’t freeze in the winter and doesn’t clog up with sand and dirt the way a screwgate does. In addition to the one-of-a-kind gate, the Magnetron GridLock also has a separated bottom and top so as to completely eliminate the chances of cross-loading, because this is one piece of gear that absolutely cannot fail. To further ensure that its safety, Black Diamond hot-forged this carabiner to make it as tough as it can be. As a final touch, this carabiner also got a keylock nose to eliminate snags when you’re taking your friend off belay.
