You need double curtain rod to hang when you have a lighter behind a heavy curtain. The shades lighter are usually lace or thin fabrics that help give some privacy to the room, while allowing light to penetrate. You can get this in different ways. You can use elastic tension rods that are inserted into the window frame without supports or fixed mounts to hold the curtain rods. The steps below describe how to install the brackets for two curtain rods.
Double curtain rod determines the height from which you want to be the (lighter) inner curtain. Check that the marks are aligned horizontally holding the curtain rod in position and placing the level on it. Sets the alignment marks if need be corrected. Place the supports for the inner curtain rod about 1 inch (2.5 cm) of window covering, at the height indicated by the pencil marks.
Double curtain rod inserts the screws through the brackets and uses a screwdriver to place. Determines the location of the second set of brackets that hold the rod for curtains outdoors. Place them about 2 inches (5 cm) wider and longer than the supports of the curtains interior, adjusting the actual extent of the curtains. Use the pencil to mark the appropriate points.
