The Black Diamond Gridlock Magnetron Carabiner combines 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.I-beam spine with a large round rope bearing surface.Made in the USA.Weight: 78 g (3 oz).Closed Gate Strength: 22 kN (4,946 lbf).Open Gate Strength: 8 kN (1,798 lbf).Minor Axis Strength: 7 kN (1,574 lbf).Gate Opening: 21 mm (.83 in).
