INSTALL DOOR
ASSEMBLE FRAME
1. On a clean and flat
surface, lay out 
frame head, sill and 
side jambs with 
the exterior side 
up. If installing a 
pocketing system, 
there will be post 
interlock(s) for each 
end that pockets 
used instead of a 
side jamb piece. 
Post interlock(s) do 
not install on the 
extreme end of the 
head and sill tracks, 
but will install to 
the side where 
the pre drilled 
holes are located 
(approximately the 
width of one panel 
from the end of the 
head and sill tracks).
2. If gaskets are
provided, adhere 
to both ends of 
the sill. Run a bead 
of silicone on all 
surfaces of the sill 
as shown. Repeat 
silicone application 
for the head where 
the ends will 
contact the jambs.
3. Clamp the frame
corners as needed 
to ensure that the 
frame sections fit 
together flush and 
using the supplied 1 
1/4" screws, fasten 
the sill to the right and left jamb frame parts. The pre-drilled holes in 
the jamb will line up with the screw bosses in the sill. Make sure the 
attached gasket lies flat and the screws are inserted properly into the 
screw bosses.
4. Using the supplied 1 1/4" screws, fasten the header to the right and
left jamb frame parts through the pre-drilled holes in the jambs.
5. Seal the screw heads and the outside of each corner joint with
sealant.

INSTALL FRAME
Warning!
To avoid injury, use at least two people to install.
1. If installing a pre-
formed sill pan, 
follow manufacturer's 
instructions and skip 
this step. If installing a 
job site fabricated sill 
pan, run a continuous 
3/8" bead of sealant 
along the sill pan back 
dam. When the frame 
is installed, make 
sure the frame makes 
solid contact with the 
sealant. Add more 
sealant if necessary.
2. Tilt the frame into the rough opening. Adequately support the frame
until fully installed.
3. Align the exterior of the frame, or applied nailing fin, with the most
exterior surface of the structure (the exterior face of the concrete 
wall, framing or sheathing).
SHIM THE JAMBS
Note!
Secure all shims with sealant.
1. From the interior,
shim the side jambs at 
each pre-drilled hole. 
Shim head track next 
to pre-drilled holes. 
Also shim at the strike 
plate(s) if applicable so 
that strike plate screws 
(installed later) will 
each penetrate a shim.
2. Inspect the frame for
square, level, and 
plumb (remove and 
reinstall if necessary).
FASTEN FRAME
1. To secure the head, fasten through each pre-drilled hole using #10 x 2
1/2" screws. Fastener holes should not go through, but next to shims. 
Move shims accordingly to be next to fastener holes if necessary.
2. To secure the sill, put a generous amount of silicone sealant in each
pre-drilled hole and drive a #10 x 2 1/2" screw through each hole.
3. Secure the side jambs through each pre-drilled hole.
6. Verify the unit is square by re-measuring on the diagonals.
7. Verify the unit is plumb and level.
8. Use a level (4 foot recommended) to ensure there are no bows in the 
framing.
9. Adjust screws and re-shim as needed to correct any bows.
