Yes they do sell this. It's typically installed at the bottom of the joist and helps the drywaller locate the rough-in. Although I'm sure it'll support the weight of the fixture and driver, I'm slightly worried. I also feel it looks cleaner if the entire thing was in the cavity of the joists. Plus, I have extra wood available.
