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?"

    My wife is a weaver for each project, she has to change her pedaling on the loom. She found your S-Biners at our local hardware store, but they were too large. She asked me to order #1's and they worked perfectly.

    Absolutely wonderful product. 0 complaints, works as expected. They're definitely better than a regular carabiner with how easily you can clip in/out of them. I use these to easily hook in water bottles. Don't need a pocket for my Nalgene anymore!

    Wonderful product, does absolutely everything you'd expect it to and nothing you don't. So far it's held onto everything I've thrown on it from rock climbing shoes to a Canon 70D all the way through the Grand Canyon. Easy as cake to use, definitely worth buying (sooooo much better than a normal carabiner).

    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.
