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

This is a great carabiner.It feels sturdy, the little locking pieces are handy and don't feel like they're going to wear down quickly, it's a reasonable size and thickness, and it's not difficult to lock and unlock when you need to.This brand also has a lot of good reviews from people in "Buy It For Life" communities for their long-lasting carabiners, and it certainly feels as though they're correct, because this feels really sturdy and well-made compared to other carabiners I've used before.

Works just as well as a heavy duty carabiner for attaching extra bags to my camping bag. Had doubts about the reliability of the locking mechanism but never had a problem dozens of times I used it.

This S shaped Carabiner it is strong and sturdy and looks great with my tassel. I will definitely purchase 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.

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 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
