I recently purchased the SHONAN Large Locking Carabiner, and I’m extremely impressed with its quality and performance. This carabiner is heavy-duty, well-built, and perfect for securing heavy loads.Pros:✅ Solid Stainless Steel Construction – Feels incredibly strong and rust-resistant.✅ Smooth Locking Mechanism – The screw-lock works flawlessly, ensuring a secure grip every time.✅ Large Size – Perfect for various applications like hammocks, outdoor gear, securing tools, or even marine use.✅ High Weight Capacity – Can handle heavy loads without any signs of bending or weakness.Cons:⚠️ A bit heavier than aluminum carabiners, but that’s expected for stainless steel durability.Overall, if you need a strong, reliable, and well-made locking carabiner, this is an excellent choice. Highly recommended for outdoor enthusiasts, campers, and anyone needing a secure attachment!💯 Would buy again!

Heavy duty used this type before, but not this brand. I use them for my safety chains for my boat trailer.

I used to have a standard carabiner for my boat launch rope, but found that it inexplicably "unbuckled" every once in a while, leaving me to swim out to my boat to retrieve it. Finally, I decided to remedy this inconvenience by getting a locking version that can't simply unhook by itself. This fits the bill perfectly. Easy to lock and unlock. Strong and well made. I should have done this a couple of years ago.

A little sharp where it closes and can pinch the rope if you aren't careful. Very strong and heavy duty

Bought these for various uses - one being to hold my keys on a belt or pants loop. They work perfectly. They are the perfect size and very sturdy with an easy locking mechanism. One of carabiners in the pack did not lock - contacted customer service and a replacement was sent out that same day. 5 stars on product and service. You can't go wrong buying these!
