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 nish 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 
nishing nails.

replace the center 
screw (as shown) in 
the top two hinges 
(through the leaves 
toward the jamb) with 
the provided 
#9 x 2½" 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 
theslab.
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 nish coats.
2. Pre-hung door 
frames extend 
below the slab to 
allow for different 
oor 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 
doorclosed.
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 nish nails 
approximately 2" 
from the top and 2" 
from the bottom of 
the jamb to level and 
temporarily secure 
inplace.
