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

Lightweight and lockable. Very sturdy construction.

Great quality, holds a lot of keys, is very sturdy, love that it has the locking feature so that nothing can fall off or come unclipped.

This is the perfect size for what I need it for. I use it to hook my pulse ox to my bungee cord (since theres not another way I can really do that and I dont have a lot in the way of room in my many pockets). This isnt its designed purpose but its very handy in the hospital.

Our yard is not fenced and when our 30 pound dog is outside we use this to put him on a long lead and he has complete freedom to roam without taking off.

Its exactly what your looking for as a key hook. Sleek, sturdy, and the locks are strong.

Work at receiving and maintaining Machine running comes in handle with the huge hook to hold or install organize and goes well with my tractable key holder.

This is a great product, if you are not me. I bought this as a replacement for one like it, because mine disappeared off of my keychain. So the locking feature sold it for me. The lock is easy to use, and works.. except today I realized I no longer have my s-biner with locking feature. It somehow figured out how to unlock itself and escape my possession. Atleast this time it went alone, with no keys. Now Im sad and have to hold my keys, and somehow not lose those too. Adulting, amirite??

I loove it! Im never losing my keys again!

Love this. Using it for my keys. Very well made. Great quility.

An excellent product for making life more easy! Ive only used it so far to hang things from cordage when camping but I can see so many other great uses. Its sturdy as well. Going to be ordering more in all sizes. Great add-on to my Prime Orders.
