The Nite Ize S-Biner Plastic #6 is a lightweight double-gated carabiner with a durable glass-filled nylon body and stainless steel wire gates, in black with black gates. The S shape gives two separate clipping ends, so you can hang one item from a hook and clip another to it, or join two things together. The #6 measures about 73 x 195 x 13 mm, a good size for clipping water bottles to a belt or backpack, hanging boots, gloves or garden tools on garage hooks, and carrying reusable shopping bags. Light, strong and handy around the house, garage, campsite and car. It is an accessory clip and is not for climbing.
