I got new windows in my daughter's room, and the new window sits closer in the window frame than the old one. I went to hang up the blinds and because the window is closer in, when I went to drill a hole for the bracket screw instead of sheetrock I got the metal strip that builders put on the edges of where the top of the window frame and the wall meet. Can I just put the screws in the metal? Do I need anchors if I screw into the metal?
Thanks!!
