Gridlock Screwgate

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.
