Nite Ize - LSB4-01-R3 LSB4-11-R3 S-Biner Slide Lock Carabiner, Black, #4

Very nice for keys

Nice S-Biner, but the slide locks do occasionally come unlocked as they rub on or move against things. It does not take much force to unlock them.

Works like it should

Love the locking feature

Great carabiner for all types of keys. The locking mechanism is great and I have not had any issues. Highly recommended

Replaced the one I lost that doesnt have locks. The locks actually keep this beaner clipped until you slide the lock down. Better improvement than the original without locks.

I use these to link bags together. I love the dual-sided locks that dont necessitate removing the entire carabiner to remove a bag.

Work is you want it just as a key chain. I used it to hold a c wrench and it ended up being the locking bars from it being in my back pocket and me sitting down

i use this for my keys instead of a lanyard and its amazing plus it is very secure because it has a locking part that prevents accidental opening

Changed out the carabiner on my key ring that clips my keys to my gear. Once I got used to the locking slides, they make pretty great clips plus, I have yet to have a drop. Ive got another on my water bottle, and it makes traveling pretty secure. Good additions to a well thought out packing scheme.
