ADJUSTING STAIRWAY TO CEILING HEIGHT
Pull stairway down applying pressure so that hardware arms are
fully extended. Open the stair sections, folding bottom section
under the middle section. The top and middle sections should
form a straight line. Aligning your ruler on the same plane as the
two upper sections, measure the distance from the bottom of the
4A). Mark the distances obtained on the front and back sides of
the ends of the bottom section.
Trim bottom sections at the proper length and angles by cutting
across them. With the bottom section cut to the proper length and
angle, joints will be tight at each section with weight on the stairs.

from the edges of the plywood door panel.
