SMC's Large Steel Locking D was developed especially for the needs of the fire and rescue communities with a large gate opening that easily fits over litter rails. 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. Features stainless steel gates and locking sleeves for greater strength and reliability plus 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. Additionally, each carabiner is 100% hand inspected for gate action and other functional characteristics before leaving our factory. If you want a carabiner that performs just as well after 100 jobs as it did the first time you used it then this is the one to buy. Available in bright plated or black zinc plated finish for tactical operations.
