One of the strongest 100% USA-Made steel carabiners on the market!
Heat-treated Large Steel Locking D was created to address the need for a very strong steel carabiner without adding unnecessary weight and size. Given the additional step of heat-treatment in order to provide an incredible 30% greater strength. With same specs as the SMC Large Locking D Carabiner platform, and certified to meet NFPA “G” General Use standards, this is the hard working, nearly indestrcutible carabiner needed in every kit.
The sleeve locks on the gate rather than the body of the carabiner, eliminating problems of the knob binding on the frame after the carabiner has been loaded. Uses “hybrid” steel/stainless steel construction; incorporating stainless steel gate and locking sleeve for greater strength, smoother action and long-lasting reliability. All the components in this carabiner are meticulously hand-finished after machining resulting in the smooth, free gate action that is the hallmark of all SMC carabiners.
