The SMC Standard Aluminum Locking D Carabiner's high-strength, light weight, and wide gate opening have made them the choice of rescuers from the high mountains to urban and industrial locations. They feature a high strength aluminum alloy frame and gate, plus stainless-steel internal parts. The nut locks on the gate, not the frame, to prevent jamming or vibrating loose.

Note: 3 Sigma MBS is a standard way of determining minimum breaking strength yielding results that are 99.87% accurate.
