This is a set of disc plates, screws, and washers for Union bindings. It is used. It works fine, but I'm selling it to organize my binding accessories. I lost one screw and used a shortened Burton genuine screw. The Burton genuine screw has a stopper, so it's a little stiff to start, but it tightens normally once it's in. It's the screw in the bottom right. Returns are not accepted to prevent swapping.
