Nice way to support 2x2's. These can be used for volleyball or badminton nets. I am using mine as a weld booth in my shop when I weld or grind. Add some 2x2's and some weld curtains..A quilt quild used them for a quilt display. With the additional piece in the photos,posts can be attached together in a maze. I do have a lot of 2x2's I am willing to negotiate. I have alot of these stands.
