INSTALLATION INSTRUCTIONS
for Interior Pre-Hung Doors
5. Level the latch side of the jamb in the same manner as the hinge
jamb. Ensure the jamb is not twisted and that the spacing between
the jamb and door is uniform on all sides. Adjust the latch side of the
jamb as necessary.
6. Shim the top of the jamb in the center of the opening and fasten
with a 10d finish nail.
7. Re-check for square, level and even spacing around the door. Nail
securely in place through the stop, jamb, shims and into the studs
every 12" – 16". Set nails with a nail punch.
8. Position trim or slide
trim assembly (two
piece jamb) into place
in the frame. Carefully
nail the trim on both
sides of the door every
12" to 16" using 4d
finishing nails.
9. After installation,
replace the center
screw (as shown) in
the top two hinges
(through the leaves
toward the jamb) with
the provided
#9 x 2 1/2" screws.
COMPLETE INSTALLATION
1. Install lockset hardware per supplied instructions.
2. Fill any nail/screw holes and sand smooth.
3. If installing a two piece jamb system, run a bead of 100%
polyurethane sealant in all joints and tool until smooth.
4. Finish all six sides of the door slab as well as the frame (if not already
done). Note! If removing the slab from the frame for nishing, remove
hinges from the jamb only, do not remove hinges from the slab.
5. Protect recently installed units from damage from plaster, paint, etc.
by covering the unit with plastic.
Warning! To avoid injury, use at least two people to install. Adequately
support the door until completely fastened.
Pre-hung doors will be either a one or two piece jamb system. One piece
jamb doors come without trim applied. Two-piece jamb doors come in
two sections. The inside and outside trim are already applied to the main
frame. The frame section with the pre-hung door is nailed in place, then
the other frame section with the outside trim slides in from the other
side and fits closely to the wall. The two sections are assembled with a
tongue and groove joint which is covered by the door stop.
One piece jamb systems skip step 1 and begin with step 2.
1. If installing a two
piece jamb system,
separate the trim
assembly from the
frame section. The
trim assembly may
be taped or tacked
to hold it in place
during shipping.
Frame components
can be lightly primed
or stained prior to
installation, but wait
until after installation
before applying finish
coats.
2. Pre-hung door frames
extend below the slab
to allow for different
floor heights. The
jambs can be trimmed
as needed before
beginning installation,
however make sure
to leave adequate
space to allow air
to pass under the
door according to
ventilation codes.
3. Remove any
packaging or nails
that hold the door
closed.
4. Position the door unit
into the opening and
level the hinge side of
the jamb. Use shims
fastened through
the jamb and stop
with 10d finish nails
approximately 2"
from the top and 2"
from the bottom of
the jamb to level and
temporarily secure in
place.
