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.
