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.

    About Me Avid Climber

    • Won't crossload


    • Hard to open

    Best Uses

    • Long Climbs
    • Outdoor climbing
    • TR soloing

    Comments about Gridlock Screwgate Carabiner:

    I like this thing except that it's clunky to get off my gear loop and onto the belay loop and then the ATC and the belay loop are in the wrong places on the 'biner. Once it's ready to go, Bomber!
