Installation Instructions
PREHUNG EXTERIOR SIDELITE DOOR
a
)
Close the door unit and re-check
the margin around the door unit, it
should be even horizontally across the
top of the head jamb and vertically
from the head to the sill. Make
adjustments to the shimming as
needed.
(
fig.25
)
.
b
)
If your prehung unit has an adjustable
sill: Using a #2 phillips screw driver,
adjust the set screws on the top of the
sill crown to allow your door to operate
properly
(
fig.26
)
. A good test for the
proper height of the sill crown is to
1.) Close the door on a piece of paper.
2.) Pull the paper from between the
sweep and the threshold
(
fig.27
)
.
If the paper tears, the threshold is
adjusted too high and it will prematurely
wear out the sweep. If there is no tension
on the paper, then there will be potential
for water leakage.

All Mastercraft doors are set up
with a 2-1/8" bore hole set at either a
2-3/8" or a 2-¾" backset (depending
on door size). All crossbores are set for
a 1" drivepoint latch. This is done to
allow installers to utilize drive point
latch systems, radius plate systems, or
square plate systems
(
fig.28
)
.

To install the backset as a drive-
point system, simply follow the lock
manufacturer's instructions for convert-
ing to a drivepoint. Hammer the
drivepoint into place making sure the
angled portion of the backset faces the
jamb

Install the strike plate on the jamb
(
fig.31
)
.
Our jambs are mortised for a ¼" radius strike
plate. If the lock manufacturer has supplied a
square plate, use a chisel to remove the excess
wood material from around the corners of
the plate.
e
)
For doors that are bored for a deadbolt, install
the deadbolt strike plate. If the door does not have
a deadbolt, install a plastic deadbolt cover plate
included with the door

Before applying casing to the interior of your door unit you
will need to insulate around the frame opening. We recommend
using “Fiberglass Blanket Insulation”. Do not use expanding
foam, it will affect the margin around the door unit
