The only worry I have with this is that it's pretty long. My windows are set into the wall a little further, so that combined with how far out this hardware sits leaves quite a gap. I was actually a little surprised with out far out it sits, it seems like it would be a little less stable or less able to carry weight but I have blackout curtains on it, and it seems fine (but with the 5 inch gap between the rod and the wall, of course more light gets through than some of the other double curtain rods)
