This carabiner is the most popular aluminum carabiner made by SMC. The components of this carabiner are meticulously hand-finished after machining, contributing to the smooth, free gate action that is the hallmark of all SMC carabiners. Each one is 100% hand-inspected for gate action and other functional characteristics before leaving our factory. Offered in three colors; Bright, Red (shown above-anodized frame with Bright gate) and Black (frame/gate) for tactical applications. All SMC NFPA products are third party tested (by Underwriters Laboratories - UL) as required by NFPA 1983 (2006 edition) standards. All SMC NFPA carabiners have the required certification information stamped on the frame and the user information is enclosed with each item as required by NFPA.
