Double curtain rods are equipped with two rods to connect to a set of brackets. A clean panel hangs behind a regular set of draperies, giving privacy when drapes are open to let the sunlight through the windows. A double bar is hung in the same way as a single rod; no extra hardware is required and all brackets and screws are included in the rod kit. If you install in an area of plaster not backed up by a frame stud, drywall anchors are required.
Measure the width of the window and add 8 inches to the total. Buy double curtain rods that come across the width of the window. Measure 4 inches above and 4 inches away from each top corner. Alternatively, mark an identical spot at each top corner of the profile above the window. Hold the mounting brackets up to each mark and mark the screw holes.
Drill holes through each screw hole are not backed by a plaster stud or casting. Use a drill bit a size smaller in diameter than the mounting screws. In the tip of a plaster wall anchor in one of the holes and carefully pound it into the wall with a hammer. Repeat; fill each hole with an anchor. Screw the mounting brackets into casting or plaster anchors. Pull back the rod through the double curtain rods pocket on the large panels and place the rod in the back bracket. Tighten the clamping screws to secure the rod to the brackets. Repeat with the front bar and panels.
