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 #10 is the largest size, about 128 x 266 x 17 mm, and it fits over closet rods, stroller handles and thick tool handles. Use it to hang and store bikes, garden hoses, extension cords, heavy tools and sports equipment in the garage or shed, or to hang bags and gear from a hook. It is a storage and organising clip, not for climbing.
