Have you noticed that the beespace, according to the catalogs, would differ whether you are using a deep, med, or short? I can't answer your question, all I can say is that I get nearly all of my frames from Dadant or Brushy Mt. (I think they are the same) and many deep frames will not measure 9-1/8 after assembly. more like 9-3/16 to 9-1/4.
