    Purchase Black Diamond Rocklock Magnetron


    The Black Diamond RockLock Magnetron uses the revolutionary Black Diamond locking system that is secured with magnets. Inserted into the nose of the carabiner is a piece of steel, while the gate 'clips' are magnets. When the gate is open the magnets oppose each other keeping the gate unlocked. When the gate is closed the magnets snap tight onto the steel insert and the carabiner is locked instantly, it is this fast secure locking mechanism that makes this carabiner super safe.

    Rocklocks feature a keylock nose which reduces snagging on the rope, and the Rocklocks large size means it is easy to fit several clove hitches on one carabiner while rigging belays. When you need a large screwgate for belaying and rigging ropes the Rocklock is the carabiner you want.

    Black Diamond RockLock Magnetron Review

    Very nice locking mechanism, easy to use even with the mitts on, making it great for winter. Unfortunately, it's very heavy and more expensive than any other locking biner on the market, and I don't think that just the lock system justifies the steep price. But for showing off or for the people who want to try something new, it's a good addition to the rack.
