Black Diamond Magnetron Gridlock

{{ vm.state.webThumbOverlay.code }}


Combining maximum security and ease of use like never before, the Black Diamond Magnetron GridLock Karabiner uses the power of magnets to reinvent the auto-locking Karabiner. Magnetron Technology uses two magnetic arms in the gate and a steel insert in the Karabiner'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 the innovative GridLock shape, which traps the belay loop to eliminate cross-loading, and the Magnetron GridLock is a fantastically useful Karabiner.
