I'm not in the studio to confirm, but as I recall one of our short Bogen background light stands has a slip on adapter. It slips right over the fixed stud in the stand and down over the shaft a little. There's a knurled set screw to lock it in place. I can't recall whether we bought it seperately or it came with the stand, but it should be exactly what you're looking for. So much of our Bogen gear is 20-30 years old that it may not relate to the current line. That kind of life span is strong reco for Bogen quality, isn't it! And by the same token, some of it is still in their line- yet another sign.
