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

Been using it to clip my car keys and work keys to my pants for almost two years now. It's pretty solid metal and has a pretty good build quality. The locking mechanism is a nice bonus and is easy to work. Some of the paint has worn off which is to be expected after 2 years of heavy use but that's not a super big concern for me. Works great for clipping keys to your belt loops. 10/10

I'm currently a delivery driver for a local miller and I use this to keep my van keys secure but accessible. I handle 50-lb sacks of flour, grain, oats, etc and haven't had any issue with the carabiner. There's a lock function too, but honestly I haven't had to even use it yet. Would buy again

I have a couple of these, they're great. 1 is always attached to some sort of bag that I have. They're low key and reliable. I like that there's a locking feature to it, I don't use it often but I like how easy it is to use it if I want it. You just slide the metal piece down to lock, slide up to unlock.

i have so many of these things, theyre the best carabiners. love the lock

I am a Sergeant in the PA Army National Guard and I have been using S biners for years, particularly this size and locking. They are excellent for carrying gloves or other things to be hands-free. I clip one end to my belt loop and the other to the loop on my gloves. *It is important to lock them when you aren't using them (you probably don't need rapid glove access), because I was doing land nav once and managed to get a stick clipped into the unlocked side of my S biner 😂.But like I said, great for other things, if I am using my gloves, I can clip a canteen or something to my belt loop hands-free which is great. That is my main use, gloves, but I am sure they'd be great for whatever you want them for

Used these to hang things off my back pack. Excellent quality.
