The Nite Ize S-Biner Plastic is a double-gated carabiner shaped like an S, with a gate at each end, so you can clip one end to a hook, strap or belt loop and hang something from the other. The body is glass-filled nylon, light and strong, and the gates are stainless steel wire. The #8 is one of the large sizes, about 95 x 205 x 15 mm, and it fits over stroller handles, closet rods and the handles of larger garden tools. Use it to hang and store bikes, hoses, extension cords, heavy tools and sports gear in the garage or shed, or to clip bags and gear together. It is a storage and organising clip, not for climbing.
