Black Diamond RockLock Twistlock Carabiner

The RockLock Twistlock, Black Diamond's largest locking carabiner, was designed for belaying, rappelling, or anchors. This one-hand operable autolocking twistlock carabiner now features a hot-forged lightweight construction to keep your harness as light as possible, a redesigned spine for better handling, and a larger rope-bearing surface for greater durability.
