With its revolutionary, patent-pending design made possible by our in-house hot forge, the Black Diamond GridLock Screwgate eliminates the dangers of cross loading. Designed specifically for belaying, the intuitive, easy-to-use GridLock isolates the belay loop behind its uniquely shaped gate, thereby keeping the carabiner in its proper orientation. The GridLock's I-beam spine transitions into a large, rounded rope-bearing surface for maximum strength and smooth rope feeding. Simply put, you'll never have to deal with a shifting, cross-loaded belay carabiner again.

    More hassle than it's worth

    Prevents crossloading
    requires more steps than other biners

    The main in-practice difference between this and other crossload-preventing biners is that the piece preventing the biner from spinning is attached to the gate. So if you lock it but forgot to pull your belay loop through, you have to unlock it to be able to pull it through. I could see how someone could easily get used to that, but my first course of action after clipping everything together pre-belay is to lock my biner. Meaning I usually forget to pull through before locking.
    I also question the structural integrity of the piece inside the biner. If you forget to pull through and that get's shockloaded, when will it break? Will it leave a ragged metal edge inside your biner? I've never seen one break like that, just voicing a concern.
