Combining maximum security and ease of use like never before, the Black Diamond Magnetron Rocklock 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 easily be used with either hand. Our classic RockLock shape is ideal for belaying, making anchors or rappelling, and its keylock nose prevents snagging on slings and ropes.
