Our innovative belay biner featuring Magnetron Technology, which uses magnets in the gate and a steel insert in the nose for unprecedented security and ease of use.
Combining maximum security and ease of use like never before, the Black Diamond Magnetron GridLock uses the power of magnets to reinvent the auto-locking carabiner. Magnetron Technology uses two magnetic arms in the gate and a steel insert in the carabiner's keylock nose to create an ultra-secure, self-clearing and redundant locking mechanism that can be easily used with either hand. Combine that with our innovative GridLock shape, which traps the belay loop to eliminate cross-loading, and the Magnetron GridLock is the ultimate belay carabiner.
