Installation Instructions
PREHUNG DOUBLE EXTERIOR DOOR
a
)
Apply a triple bead of Silicone
caulking to the sub-floor of the rough
opening
(
fig.7
)
.
b
)
Apply a second bead of caulking
around the perimeter of the door
sill
(
fig.8
)
.
e
)
Open the active door and plumb the hinge side of the unit
with a 6’ level
(
fig.11
)
.
NOTE: A door that is installed “Out of Plumb” is the most common
reason for a door unit to leak air or water.
f
)
Place shims behind the top hinge
(
fig.12
)
and tack the unit into place by
removing one hinge screw from the top hinge and installing a 2-½" wood screw
through the top hinge and into the rough opening
(
fig.13
)
.
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.
a
)
Moving the door frame as little
as possible, carefully close the active
door. Place shims behind the middle
and lower hinge locations and each of
the three corresponding hinge loca-
tions on the inactive door.
(
fig.14
)
.
NOTE: An even margin across the top of the header and down the center of the door will
ensure that the door unit is square in the opening. Uneven margins will result in the door
unit being out of square.
NOTE: The door slabs are heavy! During
the initial installation, the weight will
cause the jambs to twist, increasing the
margin between the active door and the
astragal. This twist must be shimmed out
to ensure proper 1/8" margin between
the active door and the astragal.
b
)
Continue adding shims until
the margin between the active door
and the head jamb is even and the
margin between the active door and
the inactive door astragal are even.
