Carabiner Clip 4 pcs | Strong Black Aluminium Hook D-shaped D-ring locking spring snap mechanism with screw Use:keychain, hiking, camping, traveling, fishing, lifting.

Bought these to secure zips on a backback from pickpockets, putting them through the holes in the pull tags. When they arrived the locking ring was a bit tough, catching on the thread on the main body. This eased with a little use, and with the application of a little lubricant (WD-40). After a few days they were quick and easy to use. Note that although a good size, these are light aluminium clips and definitely shouldn't be used for climbing applications.

I have a pickup truck with a cargo area that is just too long to reach the end nearest the cab. However, using cord to provide a continuous line through the cleats, together with the carabiners to hook items on and attach pull cords, enables items to be placed in the cargo space and retrieve them without having to climb in.

Nice matt finish, and cheap. The lock system is great and I know I'm not going to lose my keys. The screw on the lock system is a little sticky though hence why I give it 4 stars. But I am happy with the product.

Definitely strong and sturdy, I just didn't realise quite how big they were... But that's my fault. I'm using these to protect my dogs from easily being stolen while out on walks. Works well!!

needed 1.. got 4, haven't needed a use for the other 3 and had these for months. so I guess its working. and have spares for when and if it breaks. ideal

These are fine, I use them to attach various things to my workbelt and backpack, they're strong enough to have a light tool, water-bottle or pair of gloves hooked onto them, but these are NOT for climbing, buy proper ones for that. That is not the purpose for these carabiners.

Great carabiner. The locking mechanism is the best I have seen. Had a few carabiners that have had the springs broken withing a few uses, however these are still going strong a year in. Have been very useful. Would recommend

Has a little bit of scratches at the lock and lock seems quite loose by making squeaky sounds as I lock it up, but it is light and it closes tight which I'll have to test it out later on
