Most ski bindings have ski brakes that hold the skis together. The Button Hangers uses this to store a pair of skis. One ski hangs by the ski binding toe piece. The other ski hangs, on the suspended ski, by the ski brakes. Some ski/ski brake combinations may need a strap or clip to help keep the skis together.
Options: Button Hangers have traditionally been made from wood and sold together as with a wall mount backboard. The new injection molded Button Ski Hangers come as individual pieces that will allow you to build your own Button Ski Rack® out of a board from the hardware store, an old ski, a 4×4 post, a railing on your deck, etc.
Prebuilt backboards can be purchased at etsy.com as well. These back boards are slotted to give you the freedom of adjusting the spacing between buttons.
