Installation Instructions

a
)
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.
b
)
To install the backset as a drivepoint system,
simply follow the lock manufacturers instructions
for converting to a drivepoint. Hammer the drive-
point into place making sure the angled portion
of the backset faces the jamb
(

)
.

Using the manufacturers instructions, install the
lockset
(

.

Your double door unit will arrive with strike
plates pre-installed on the astragal. Depending on
the installation of the door unit, these plates can
be adjusted using a #2 phillips screwdriver. Loosen
the plates and slide them up or down as needed
(
fig.32
)
.
NOTE: If you are changing your strike plate for a
different nish or style, adjust screwdriver torque
setting accordingly to prevent screw head damage.
PREHUNG DOUBLE EXTERIOR 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 header and
vertically from the header to the
sill. Make adjustments to the shim-
ming as needed.
(
fig.18
)
.
a
)
Place 3 shims across the head of the door
unit. Make sure not to over-shim the head of the
unit or it will interfere with the margin across the
top of the door. Open both doors and hold back
the weather strip.
(
fig.21
)
. Install one 2-1/2"
drywall screw into the head and through each of
the shim locations. Screw holes can be filled for a
more finished look.
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.19
)
. A good test for the compression of
the sweep on 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.20
)
.
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.

Double door units are equipped with an astragal that acts
as a stop for your active door. This astragal is supplied with
head and foot pins that secure your unit in a fixed position
when the pin is extended. You will need to drill a hole into the
frame head and sill for these pins to operate.
To locate where your pins will set into the frame, put a dot of
white paint on the end of the pin
(
fig.22
)
. Swing the door
to the closed position and extend the pins out, marking spots
on the sill and header
(
fig.23
)
. Drill a 15/32" hole into
the sill crown
(
fig.24
)
and a second 11/32" hole into your
header. Finish using silicone adhesive to secure plastic sleeve
(
fig.25
)
into the sill crown.
b
)
A strike plate will need to be mortised into the head of
the frame. First apply the strike plate centered over the hole
you just drilled
(
fig.26
)
. Next using a utility knife, score
around the edges of the plate
(
fig.27
)
. Remove the plate and
use a chisel to remove the desired amount of wood
(
fig.28
)
.
Re-apply the plate and secure with screws
(
fig.29
)
