The Rock Exotica RockD Auto-Lock Aluminum Carabiner in lanyard pin version features a .5" round bar stock giving the carabiner a durable work profile, while providing the high strength characteristics of the "D" frame shape. It is a specialized carabiner designed for attachment to lanyards or hardware to prevent cross loading of the gate. Install gear or lanyards with the peace of mind of a secure, semi-permanent capture. The exclusive design enables the lanyard pin to be removed, allowing the user to attach the carabiner to any object. Features include a narrow asymmetric "D" shape to optimize MBS, high strength-to-weight ratio in a standard size carabiner, and a snag-resistant keylock nose design. Large and ergonomic angled gate opening and machined frame ensures tight tolerances and smooth operation.
