Nite IzeBiner SlideLock Locking Stainless Steel Carabiner (Black, #2)

Very secure and lockable perfect for my rucksack. Worth the value in money.

Small but really handy, well made too.

Brilliant. Its the locks on the springs that are clever and effective. Size difficult to gauge from the photos (should have looked at the tech spec) so got one slightly small (#2) and one (from another source) rather large (#4). Obviously I need a #3 to fit on my belt loop.

I initially purchased the standard version but found them too unreliable. After some searching, I came across these, and I couldn't be happier. They have a clever design where you can push a small plastic tab down to lock the opening, making them much more secure. I use these to attach a small EDC light to my belt for nighttime use, and they perform flawlessly.

I brought these specifically for the slide lock, as I have the tendency to loose items when I hook onto my backpack. Traditional carabiners break easily. This Nite brand is top quality, a bit pricer but very reliable. I secured my travel neck pillow onto my backpack for the whole duration of my trip and it never came undone. I love the side lock which adds another layer of security. The size is a little large but is fine. I have also tested with my water bottle and it holds it well.

After ≈ two weeks of holding a water bottle to a bag (high use though well under the 10 lbs limit), the gates broke off. Before this, the gates did repeatedly lock on the wrong side of the bar which required fixing with brute force.I'd just get a normal carabiner.

This was the other clip my uncle wanted. Dont know what he would've done without it, probs go hardcore👍

Bought this as an extra measure of security on a backpack zipper. Works well and I'm sure that if someone decides to try and help themselves to my backpack contents I'll notice.
