BROTREE Locking Carabiner Clips 12KN (1200 kg) Heavy Duty Carabiners for Hammock, Camping, Hiking, Backpack and More (2 or 4 Packs)

I use these to secure my dogs leash to the floor anchors in the back of my small van. Means that when I open the rear door, if a dog hops out then they can’t run into the road.Also great for connecting both their leash handles together, or securing a collar to another for safety. Even better that they lock by twisting, good size and sturdy enough for what I need (28kg and 35kg dogs)

They are very strong. Even though they are not rated for towing they work great but make dont exceed the weight limit. Great for keys too

I’ve been using the BROTREE Locking Carabiner Clips for a few weeks now, and they’ve exceeded my expectations in every way. These carabiners are incredibly sturdy, with a 12KN strength rating that gives me complete confidence when using them. Whether I’m hiking, camping, or simply organizing gear, they’ve proven to be reliable and durable.The locking mechanism is smooth and secure, and I appreciate how easy it is to operate even with gloves on. The overall build quality feels premium, and they show no signs of wear after regular use.These carabiners are also versatile—they’re great for outdoor adventures, but I’ve found them equally handy for indoor use, like hanging equipment or securing items. The compact size and lightweight design make them convenient to carry, yet they’re strong enough to handle heavy-duty tasks.If you’re looking for high-quality carabiner clips that offer strength, safety, and versatility, I highly recommend giving these a try. They’re well worth the investment!

Personally wouldnt trust the rating on the side of them, but im using them to hold my keys at work, so they are more than capable of that.Rotating Lock mechanism seems a little slack on the threads, as though the tolerances are too big, but again it works for what I need it for so certainly no complaints

BROTREE Carabiners: Strong Enough for My Gear and My MulletWhen I ordered the BROTREE Locking Carabiner Clips, I wasn’t just looking for utility—I wanted reliability. After all, when you’ve got a mullet as majestic as mine, you need gear that can live up to your standards. And let me tell you, these carabiners delivered.First, the specs: 12KN of strength (that’s 1200kg, apparently enough to hang a car, or at least my overstuffed backpack and hammock). The screw gate mechanism is smooth and locks securely, so I didn’t have to worry about my gear—or my pride—falling to the ground. Testing their durability, I hung my hammock, my camping gear, and, for reasons that will forever remain unclear, a Savoy cabbage. The carabiners didn’t flinch.The lightweight aluminum design makes them easy to carry.In short, the BROTREE carabiners are dependable, sturdy, and stylish enough to complement my flowing locks. Whether you’re camping, hiking, or just securing random produce, these carabiners won’t let you—or your cabbage—down. Five stars.Regards

Purchased to hang a child’s swing, sturdy and save as they lock

Slightly smaller than expected

I use it first my car keys. It does the job. I'd like to think I'm ready and prepared to climb buildings and the urban jungle... on the way to work. Haven't tested the loads bearing yet.
