: But it looks like some of the Unistrut hardware you suggested will
: do just what I want.
Now that I look at it, I'm remembering why I decided against the
wheeled options. The clearance needed between the joist and the top
of the moving panel is the problem. Here's the numbers, with all
dimensions in 1/8" for easy comparison
T-Track: 6/8" x 3/8", 3/8" clearance,
or I could inset the track into a dado for "zero" clearance.
Unistrut: 13/8" x 13/8", 13/8" clearance
13/8" is wider than the "two by", so instead of a dado
I'd have to cut off the bottom of the joist.
Curtain track: 13/8" x 5/8", 14/8" clearance (Thanks, Pete!)
I think I'm back to the T-track, with occasional applications of
TopCote (Thanks, Leon!).
The hardware isn't that expensive, so if it doesn't work I can always
go to plan B.
