Establish Door Sill Reference Point

What happens here

Place the bottom end of the story pole flush against the main house structure, specifically at the desired finished deck height, such as the bottom of the door sill. Ensure the story pole is held perfectly plumb (vertical). Adjust the laser detector on the story pole by sliding it up or down until it intercepts the laser line, indicated by a continuous audible signal from the detector. Use a pencil or marker to clearly mark this point on the story pole. Label this mark "DOOR" to signify the fixed reference height of the finished deck surface.

Goal: Define the finished deck height on the story pole.
