Black Diamond Gridlock Screwgate Carabiner
With its revolutionary, patent-pending design made possible by an 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. The ergonomic design enables easy locking with one hand only and a comfortable grip. Its oval shape was designed with the intention to balance weight, strength and size.
