The SMC Safety Lock Carabiner utilizes a double locking mechanism that meets OSHA fall protection requirements.

To open the gate, pull the sleeve to the unlocked position, then twist the sleeve and open the gate. Made with the same zinc-plated corrosion resistant frame, stainless steel gate and locking sleeve as our popular Large Steel Locking Carabiner.

The components in this carabiner were meticulously hand-finished after machining, contributing to 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.

I Feel so safe with this Carabiner

figuring out the auto lock with one hand took some time. everyone i work with that does not use them hates them. but the people that do feel really safe. and the wide gate is very nice, i hardly ever use webbing anymore to go around larger anchor points. awesome Carabiner
