Install the brackets for the top rod above the glass panes. Position the brackets so the bottom edge of the bracket plate is 2 to 3 inches above the top of the window pane. Position the brackets approximately 1 inch away on the diagonal from the outside corners of the window panes. Make sure the brackets on either side of the French door window are located in the same spot, relative to the window. This will ensure that the rod is installed evenly and level from side to side. Install the bottom rod in the same manner.
Drill pilot holes, using the brackets as a template. The holes should be about 1/4 inch deep and slightly smaller than the screws for hanging the brackets.
Position the brackets, insert the screws and screw them into the door with a manual screwdriver.
Install the bottom set of brackets approximately 2 to 3 inches below the bottom of the panes of glass and set about 1 inch away from the outside corners.
Insert curtain rods in pockets at the top and bottom of the curtain panels.
Hang curtain rods from slots in the brackets on either side of the glass. Hang the top rod first, then the bottom rod.
