Installing a bay window curtain rod is a simple task that requires no special tools or advanced skills. The components of a bay window curtain rod set include three expandable rods and four mounting brackets. The brackets that are installed on the sides of the central window receive both the central and left- or right-side curtain rod. The bracket is hinged to accommodate windows set at various angles. Installation can be accomplished in under an hour by even a novice do-it-yourselfer.

Skill level:
Moderately Easy

Things you need

  1. 1

    Determine where you want to position the curtain rod in relation to the top of the window. Faintly mark the position of a side mounting bracket on the wall with a pencil. Measure the distance from the top of the window frame to the mark and from the side of the window frame to the mark. Transfer measurements to mark the positions of the other mounting brackets so the curtain rod will be level and symmetrical. The centre-rod hardware will be mounted over the central window, as close as possible to the angle between the windows.

  2. 2

    Locate and identify the left, right and centre rods. Arrange the bay window rod components on a flat surface, just as they will be installed above the window, with the appropriate mounting brackets in place. Using your reference marks, hold a mounting bracket on the wall or window frame. Mark the position of the hardware's screw holes by passing the pencil-tip through each screw hole and making a dot on the wall. Remove the bracket. Repeat until screw hole positions are marked for all four brackets.

  3. 3

    Drill horizontal pilot holes through each screw hole mark on the window frame or wall. If the hardware is mounted directly to drywall without wooden backing, drill a hole that is large enough to accommodate a plastic wall anchor. Insert the anchor into the hole. Repeat to make screw holes for each of the brackets.

  4. 4

    Install a central hinge bracket first by aligning the mounting bracket holes to the holes in the wall or window frame. Pass a screw through the hole in the bracket into the corresponding hole in the wall or window frame. Tighten the screw with a screwdriver. Repeat to install the second central hinge bracket. Install the outer brackets in the same manner. With all mounting hardware installed, you are ready to hang the curtain.

  5. 5

    Thread or otherwise suspend curtains on the rods. Place the holes on the ends of the central rod onto the hinge-pins on the central mounting brackets. Place the holes in the central ends of the side rods on the hinge pins and hang the outer ends of the rods on the outer mounting brackets. Evenly distribute the curtain fabric to complete this project.
