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

Extremely useful.

Nothing works better that the Slide lock. We use it for lots of different things.

I was looking for a way to hook my keys onto my belt loop, and this seemed to be a good option that was also cheap. So now, having used this for about 3 months, I can say I really like it. I will admit that I went a bit overkill and bought the 75lb version (black), but it gives me the flexibility to use it for heavier things as well. As for the locking mechanism, that also works really well, even if it may be a bit difficult to get out of the way when youre attaching something. Overall though, I definitely recommend this product!

Great to use for keeping your keys ON the carabiner! Locks in place and keeps keys from sliding off of the jaws from opening accidentally. I bought 4 for our key sets at work.

They worked out great. Used them to hang a banner at our church. Great product.

I would never recommend this for a key chain. Had it several months and just started losing keys , key fobs , any on the loops. Not good.

Item was as described, works well and locks well to keep key chains from falling off, shipped quickly

They are perfect for my golf bag

Perfect solution to the s beaner. Ive lost keys while using the regular s beaner. This one locks and hasnt caused me to lose anything. Just lock it and it stays put.

I keep finding uses for it in the garage, might have to get another 1 or 2
