I love these curtain rods because they swing out of the way when I want to open the curtains. They're the best invention ever! I also like that it is adjustable to accommodate curtains up to 38" in width. Great price for 2 curtain rods!
The rods will handle sheer material out to the 38 inch spread. If you want to hang room darkening or thermal panel you will need to elevate the finial end to compensate for the slop in the pivot end and the weight of the panel. This works but one shouldn't have to compensate for sloppy Oriental craftsmanship.
