The rockD ANSI Stainless carabiner combines the heavy duty ANSI gate with the compact strength of the rockD frame. ANSI Z359.12 (09) certified. The rockD Stainless is the right choice for a strong, compact carabiner, tough enough to hold up in the harshest of environments. The narrow, asymmetric "D" shape concentrates the load along the spine, which maximizes the strength of the carabiner along the major axis. Not only is the frame made from stainless steel, but also the components within the carabiner. Each piece will resist corrosion far beyond the equivalent materials found in other non-stainless carabiners. The rockD features several unique Rock Exotica design elements: snag-resistant keylock nose design, lock-status indicator, precision machined frame, and an angled gate for maximum gate opening.
