I recently picked up an industrial and scientific-grade carabiner FROM this hardware store and have been using it on my outdoor adventures. According to my experience this carabiner is incredibly durable and can hold a good amount of weight. It`s been great for my hammock, as well as attaching gear to my backpack... The zinc galvanizing ensures it doesn't rust or corrode easily, making it a reliable option for any outdoor enthusiast. The only con is that it's a bit on the heavy side, but the durability and versatility make up for it..
