I don't know about this one, but I have the other wooden floor stand, the less expensive one ( the one that shows just the adjustable clamp on the top. Have had it since before Q-Snaps were probably invented, when I used scroll frames). It is here on this site too, although mine came from Hobby Lobby MANY years ago.
I also use Q-Snaps exclusively, & have never had a problem using this floor stand.
