FOR CENTER HINGE(S):
Starting with a center hinge, flip the upper hinge leaf up. If needed
use it as a template, mark and pre-drill (2) 9/32” diameter holes through the section. Attach
the upper hinge leaf to the section using (2) 1/4” - 20 x 1-7/8” carriage bolts and (2) 1/4” -
20 flange hex nuts. Repeat same process for the other Center Hinges.
FOR HALF CENTER HINGE(S):
Flip a upper hinge leaf up and use it as a template. Mark and
pre-drill (2) 1/8” pilot holes, 1” deep into the section with a 1/8” drill bit.
IMPORTANT:
BE EXTREMELY CAREFUL NOT TO DRILL THRU THE SECTION. ONLY DRILL 1”
DEEP.
Attach the center hinge upper leaf to the section using (2) 1/4” - 14 x 1” lag screws. Repeat
same process for other half center hinge(s).

FOR GRADUATED END HINGES:
Starting with the outer graduated end hinges, flip the up-
per hinge leaf up. If needed use it as a template, mark and pre-drill (2) 9/32” diameter holes
through the section. Attach the upper hinge leaf to the section using (2) 1/4” - 20 x 1-7/8”
carriage bolts and (2) 1/4” - 20 flange hex nuts. Repeat same process for the other side.
IF YOU HAVE DOUBLE GRADUATED END HINGES:
Flip the inner upper hinge leaf up and
use it as a template. Mark and pre-drill (2) 1/8” pilot holes, 1” deep into the section with a
1/8” drill bit.
IMPORTANT:
BE EXTREMELY CAREFUL NOT TO DRILL THRU THE SECTION. ONLY DRILL 1”
DEEP.
Attach the inner upper hinge leaf to the section using (2) 1/4” - 14 x 1” lag screws. Repeat
same process for the other side.
Repeat same process for other sections, except top section.

Stacking Top Section
11
Place the top section in the opening. Temporarily secure the top section by driving a nail into
the header near the center of the door and bending it over the top section. Now, flip up the
graduated end hinge and center hinge leaves, hold tight against section, and fasten center
hinges first and end hinges last (refer to step, Stacking Sections). Vertical track alignment is
critical. For 2” track, position flag angle / wall angle between 1-11/16” (43 mm) to 1-3/4”
(44 mm) from the edge of the door; tighten the bottom lag screw. For 3” track, position flag
angle / wall angle between 2-3/16” (56 mm) to 2-1/4” (57 mm) from the edge of the door;
tighten the bottom lag screw.
Flag angles / wall angles must be parallel to the door sections. Repeat same process for
other side.
IMPORTANT:
THE DIMENSION BETWEEN THE FLAG ANGLES MUST BE:
FOR 2” TRACK APPLICATIONS:
door width plus 3-3/8” (86mm) to 3-1/2” (89 mm) for
smooth, safe door operation.
FOR 3” TRACK APPLICATIONS:
door width plus 4-7/8” (124mm) to 5” (127 mm) for
smooth, safe door operation.
Complete the vertical track installation by securing the jamb bracket(s) or slots in the wall
angle and tightening the other lag screws. Push the vertical track against the track rollers so
that the track rollers are touching the deepest part of the curved side of the track; tighten all
the track bolts and nuts. Repeat for other side.

NOTE:
Depending on your door, you may have Fully Adjustable Flag Angles, Riveted Vertical
Track Assemblies or you may have Angle Mount Vertical Track Assemblies. Refer to Package
Contents / Breakdown of Parts, to determine which Flag Angles / Vertical Track Assemblies
you have.
WARNING
DO NOT RAISE DOOR UNTIL HORIZONTAL TRACKS ARE SECURED AT
REAR, AS OUTLINED IN STEP, REAR BACK HANGS, OR DOOR COULD FALL
FROM OVERHEAD POSITION CAUSING SEVERE OR FATAL INJURY.
FOR FLAG ANGLES:
To install horizontal track, place the curved end over the top track roller
of the top section. Align the bottom of the horizontal track with the top of the vertical track.
Tighten the horizontal track to the flag angle with (2) 1/4” - 20 x 9/16” track bolts and (2)
1/4” - 20 flange hex nuts.
