The rockD is the carabiner of choice when seeking the highest strength in a standard-sized aluminum frame. The rockD carabiner serves the broadest range of specialized uses. The rockD in non-lanyard versions features a flattened shape with an i-beam profile at the bottom and top bends, giving the carabiner a sleek profile, while providing low weight and high strength characteristics. The ORCA is a unique gate system that lifts up and twists just like many traditional auto-locks, but can be set to remain in the unlocked position. This allows the gate to open easily, just like a non-locker, but close with the security of an auto-lock.
