Installation Instructions
INTERIOR DOUBLE DOOR SYSTEM
Place shims directly behind each of the six hinge
locations
(
fig.18
)
. Place three additional shims
across the head of the door unit.
(
fig.19
)
Keep
the shims as flat as possible during the
installation in order to prevent twist on the jambs.
NOTE: Door units are heavy. If this step is not
performed the door slab may sag in the opening
over time.
With the doors in the closed position, mark the center of the ball catches on the header frame. Using the ball catch plates, provided in the
MASTERCRAFT
®
hardware bag, center the plates over the ball catch locations and mortise as needed.
Doors with astragals: With the inactive door open (door with the astragal), raise the head pin
about 1/4". Using a black permanent marker, color the top of the head pin
(
fig.22
)
. While the
marker is still wet, lower the head pin and close the door tightly. Raise the pin until it touches
the head jamb. This should leave a black circle on the head jamb
(
fig.23
)
. Use a punch to
mark the center of the head pin and then drill a 5/16" hole
(
fig.24
)
. Next, place the strike
plate so that the center hole in the plate is directly over the hole drilled
(
fig.25
)
. Screw the
strike plate into place and use a utility knife to score around the edge of the plate
(
fig.26
)
.
Remove the plate and use a small wood chisel to remove any undesired wood
(
fig.27
)
. Once the
strike plate has been properly mortised, screw the strike plate back into place. Repeat this process
for the foot pin.

)
Remove one hinge screw from each of the six hinges on the
hinge jambs. Replace the screws using one 2-1/2" construction
screw on each hinge. The screw should pass through the hinge
shims and into the rough opening stud
(
fig.20
)
. To fasten the
head jamb. Pre-drill through the door stop in the location of
each of the three shims. Nail the head into place by using
2-1/2" finishing nails.
