into the subfloor

. Repeat this process for the head of
the door where the door and sidelite are mulled together and at
each sidelite jamb locations.

Install one 2-½" wood screw into each of the pre-drilled
locations. Be careful not to over tighten the screws so that you

Once the head and sill of the door are held into
place, use the 1/8" drill bit to pre-drill a hole
through the jamb and into each of the shim locations at a 45º
angle. Once the holes have been drilled, install one 2-½" wood
screw at each of the shim locations
(

)
.
NOTE: We recommend the use of screws when installing your Prehung unit.
Screws allow you the opportunity for easy removal if adjustments need to be
made to the installation.
NOTE: Because of the angle of the screws, be careful not to draw the door
unit out of plumb when tightening the screw heads. Do not over-tighten.
