These are slightly smaller and lighter than a traditional climbing-rated carabiner.
Rated to 1100 lbs.
Sold by the pair.
A few customer reviews from Warbonnet's website:
I ordered a set of these carabiners with my hammock purchase and was surprised at the size and weight being so small & light for an 1100 lb. rating. It definitely makes the hanging of the hammock fast and easy with the webbing/buckle system.
I have found the Warbonnet Carabiners to be the most effective and affordable carabiners on the market for hanging hammocks. I particularly like that there are no sharp edges that might present a risk to the straps or hammock. They contribute to my being a happy hammock camper… 🙂
