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

Use it to carry my car keys, pepper spray, and house keys. It’s made well and I would definitely recommend.

I use this to clip my keys to my belt loop, and I had used the original design prior to this, and I often found my keys nearly coming unclipped. The locking function is strong and keeps everything secure! Great design!

Great product. I use for work daily.

Not bad for light weight.

Awesome S hook

The locking s biener is great for my keys, I dont drop them anymore.

This thing is fantastic. After months of use I havent seen any wear on the locking mechanism. Even if it wore off tomorrow and stopped working it was definitely worth the money.

The locks are a great improvement over the original S-Biners as I had my cellphone case, keys, etc. unlatch from the older version hooks (without the locks). The new versions locks slide easy enough with just the right amount of tension. I have used it for a week without an hassles. I feel a lot safer now. The slides will probably wear down after a while with use, but they are not expensive to replace.

Perfect to snap my water bottles on my backpack and not worry about losing them.

THE LOCKING FEATURE IS A GREAT IMPROVEMENT OVER THE STANDARD S-BINER. PREVENTS THE LOSS OF VALUABLES ATTACHED AS LONG AS YOU KEEP YOUR EYE ON THE LOCK AND THAT IT IS PROPERLY ENGAGED. STRENGTH AND DURABILITY ARE IN KEEPING WITH OTHER S-BINERs. WOULD RECOMMEND IF YOU ARE IN THE HABIT OF LOOSING VALUABLES OFF YOUR STANDARD S-BINER.
