Place the stair tread upside down on a work surface. On the back edge of the tread, mark 2 inches from both ends. By spacing the mounting holes 32 inches apart, you have a better chance of being able to drive screws into wall studs.
We used this stair tread at its full length for the window shown. For a wider window, use a longer stair tread. For narrow windows, ask a Lowe’s associate to cut a stair tread to fit.
Place a bracket with the end of the mounting board flush with the back edge of the stair tread near one of the marks. Align a ruler or straightedge with two mounting holes and the edge mark. Mark the bracket position on the shelf and repeat for the other end.
Glue the bracket and tape it in place on the stair tread until the glue dries. Repeat for the other side.
Apply the finish of your choice (Michigan Ave. shown). Hold the shelf level beneath the window and mark the screw hole locations. Check for wall studs beneath the marks and add wall anchors as needed. Then screw the brackets to the wall.
To hide the screw heads, consider inserting wooden buttons painted to match the brackets.
