Measure the length and width of the glass on the French door. Add 4 inches to the length, and 2 inches to the width. This is the size curtain you will need for each door.
Mark a drill location with a pencil. The mark should be 2 inches above or below the glass panel, and extend 1 inch wider than the glass.
Draw a straight line between the top left and top right drill marks. Place a level on the line to make sure the line is straight. Repeat the process for the bottom left and bottom right drill marks.
Drill pilot holes in the French door using an electric drill.
Screw the rod mounts into each pilot hole, using the included screws and an electric drill or a Phillips screwdriver.
Slip the each rod through the top and bottom rod pockets of the curtain.
Insert the end of each rod into the rod mounts.
