Snowboard binding, UNION BINDING CO.'s STRATA model, for freestyle riding - Brand: UNION BINDING CO. - Model: STRATA - Color: Gray (EARTH) - Type: Snowboard binding - Size: M Thank you for viewing. This is the Union STRATA 20-21 model. Used about 5 times per season, for a total of about 20 times over 4 seasons. There are minor scratches from use, but no damage that affects use. The screws for attaching to the board have some rust. If you are concerned, you can purchase replacements at a home center. I used these bindings attached to the November D4 board, which I am also listing. Thank you for your consideration.
