Black Diamond Magnetron GridLock Carabiner Platinum Twistlock with Locking Arms, Purple/Green/Orange/Blue

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 Black Diamond innovative gridlock shape, which traps the belay loop to eliminate cross-loading, and the magnetron gridlock is the ultimate belay carabiner.
