Nite Ize S-Biner Stainless Steel Carabina All the Usefulness of a Single-Gated Carabiner... Times Two! Our unique, two-in-one S-Biner offers functionality for a nearly endless variety of uses. Made of high quality, weather-resistant stainless steel, this ultra-handy accessory with its dual spring gates will hold, secure, and connect everything from house keys and cell phones to technical camping gear. Attach valuables to the center bar for ultimate security, link gate ends to a second set of items and anchor, or connect many items together. Smaller-sized S-Biners are excellent for connecting two zipper sliders on backpacks, duffels, and suitcases. We know that one size doesn't fit all, so we've designed five different sizes so you can choose the right size for the task at hand. We've found that the smaller sizes work great for hanging smaller items from a purse or backpack strap, attaching to individual keys, or hanging a plant from a ceiling hook. The larger sizes work great for bigger jobs like hanging a paint can from a ladder or a tool to your tool belt. But, the list goes on and on.
