DescriptionCombining 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.

Rated 4 out of 5 by David from It works, but awkward I'm very excited for this stealthy looking addition to my rack! Pros: - It is almost impossible to stop it locking when you remove your hands (hint: squeeze the magnets into their beds when the gate is open to make the carabiner lock gate-open) - Nice to save time on screwing in the gate - It looks cool - Definitely stops cross-loading Cons: - Because it's so good at locking, it's quite awkward to get the belay loop into the protected section. It's also awkward to get the rope into the belay device - you end up unlocking it three or four times to set up a belay - Heavy - Not smooth and round for the rope to run over (e.g. vs Petzl Attache) - Not useful as a general biner

Rated 5 out of 5 by ZachClimbs from Favorite Belay Biner This carabiner is by far my favorite for belaying. The magnets are fail-safe, and having my belay loop separate from my device gives me so much piece of mind! Pros: -Will never cross load if set up correctly -Easy to use, doesn't take much time. (Unlike screwing and unscrewing a traditional gate.) -Looks cool! (Mine is silver with the blue magnets) Cons: -The lockout part of the arm is great, but if you do have someone belay on it who loads it wrong it WILL break. The first time. Immediately. This is what happened to my first one and I bought another because it is so good!
