The Nite Ize S-Biner Stainless Steel is an ultra-handy accessory constructed of high quality, weather-resistant stainless steel featuring dual spring gates that 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. 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.
