S-Biner - Stainless Steel


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.

Product Information

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 six 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. We think Backpacker Magazine said it best when they wrote "Don't ask yourself if you need this useful little widget. The question is: how many?"

    These are great things to have. I've used the #4 for 101 things and counting. Carry this and some 550 cord around,and you can do a ton of things. Great job,Niteize!

    I love these things! I use the smaller ones for house/car keys, the larger to clip onto a water bottle or to clip my keys in my purse.

    Bought 4 of these little guys to secure a tarp on the back of my truck. I had just bought a new engine and transmission and needed to keep the tarp secure and these held up perfectly! I am looking forward to years of load control service from the #4 S-Biners. Thanks Nite-Ize.
