I have the Nolting 30 inch Pro. I do not have a dead bar. I'm not sure what that is. My frame has three rollers. One for both ends of the backing and one for the top. All I have to do is roll my bar up with a handle to different heights as I quilt. And to advance my quilt, I just ratchet it up. It is a neat set up and works great. I can do a large panto. The Nolting fun machine has a 15 inch throat and works great for about. If you haven't, you might want to check it out.
