With its revolutionary, patent-pending design made possible by BD's 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.
Since 1957, Black Diamond have been making some of the finest climbing equipment, ski gear and mountain accessories in the world. What began with a backyard anvil and a hammer, has now grown into a global company with offices on three continents. Yet the company is more than just for climbers and skiers, it stands for the spirit of sports we live, their values and goal, past, present and future.
