If you love the ever popular NFPA Lite Alloy Carabiner, you will love the DUALGUARD™ and TRIGUARD™ Lite Alloy when you are looking for auto-locking carabiners. The frame for these auto-locking carabiners are the same design as the NFPA Lite Alloy screw gate carabiner; strong, but light weight and smaller so that it fits in one hand without being difficult to handle. These two auto-lock designs are representative of SMC’s commitment to manufacturing only the best carabiners in the world.
The DUALGUARD™ and the TRIGUARD™ carabiners feature an internal gate and sleeve mechanism that insures smoother and more reliable opening action throughout the life of the carabiner. In addition, the gate/ sleeve mechanical components are made from stainless steel to assure longevity even when used in the harshest of environments. The DUALGUARD™ is a two-stage auto-lock that operates with easy one hand motion by twisting the sleeve and opening, all while in the palm of your hand.
