These swing straps are made of industrial-grade polyester, a durable material that can hold up to heavy weights. Wider straps deliver better balance, while reinforced stitching ensures they can withstand harsh winter and summer weather. The D-rings and carabiner hooks are crafted from stainless steel. The straps come with two tree protectors with velcro that create a protective layer when hanging gear, the metal fabric rings have extra stitching for added sturdiness, making the straps a reliable attachment that will not split at the seams. No drilling or tools are needed to install this safe tree swing hanging kit, which combines all-weather webbed straps with extra-strong carabiners. It is portable and includes a carrier bag for safekeeping, letting you easily set up outdoor fun with the long straps.
