assemblies / bottom slot in the angle mount to jamb, maintain 1/2” to 3/4” spacing, between
the bottom section and vertical track.
Stacking Sections
10
NOTE:
Refer to door section identification, located in the pre-installation section of this
manual to determine what size section you need to use as your intermediate I (second),
intermediate II (third) and intermediate III (fourth). Measure your section to make sure it is the
correct height as indicated on the chart.
NOTE:
Make sure graduated end and center hinges are flipped down, when stacking another
section on top.
With assistance, lift second section and guide the track rollers into the vertical tracks. Keep-
ing the sections vertically aligned, lower section until it is seated against bottom section.
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 2-1/2” 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 2-1/2”
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.
Attaching Horizontal Tracks
12
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.
IF YOU HAVE ANGLE MOUNT:
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 angle mount with (2) 1/4” - 20 x 9/16” track
bolts and (2) 1/4” - 20 flange hex nuts.
Next level the horizontal track assembly and bolt the horizontal track angle to the first
encountered slot in the flag angle / angle mount using (1) 3/8” - 16 x 3/4” truss head bolt
and (1) 3/8” - 16 hex nut. Repeat for other side. Remove nail that was temporally holding the
top section in position.
IMPORTANT:
FAILURE TO REMOVE NAIL BEFORE ATTEMPTING TO RAISE DOOR COULD
CAUSE PERMANENT DAMAGE TO TOP SECTION.
Adjusting Top Fixtures
13
NOTE:
Refer to Package Contents / Breakdown of Parts, to determine which Top Fixtures
Assemblies you have.
With horizontal tracks installed, you can now adjust the top fixtures. Vertically align the top
section of the door with the lower sections. Once aligned, position the top fixture slide(s), out
against the horizontal track. Maintaining the slide’s position, tighten the 5/16” - 18 hex nut(s)
to secure each of the top fixture slide(s) to the top fixture base(s).
COUNTERBALANCE
INSTALLATION INSTRUCTIONS
Attaching Rear Back Hangs
14
Raise the door until the top section and half of the next section are in the horizontal track
radius. Do not raise door any further since rear of horizontal tracks are not yet supported.
WARNING
RAISING DOOR INTO THE LOOSE HORIZONTAL TRACKS CAN RESULT IN
DOOR FALLING AND CAUSE SEVERE OR FATAL INJURY.
Clamp a pair of locking pliers onto the vertical tracks just above the second track roller on
one side, and just below the second track roller on the other side. This will prevent the door
from raising or lowering while installing the rear back hangs.
Using the chart below, select the appropriate perforated angle (may not be supplied). Fabri-
cate and install rear back hangs, as shown.
NOTE:
If an opener is installed, position horizontal tracks one hole above level when securing
them to the rear back hangs.
Perforated Angle Gauge Weight Limitations For Extension Springs:
Perforated Angle Gauge
Door Balance Weight
1-1/4” x 1-1/4” x 15 Gauge
220 lbs. to 440 lbs.
1-1/4” x 1-1/4” x 16 Gauge
175 lbs. to 350 lbs.
WARNING
MAKE SURE BACK HANGS ARE BRACED SUFFICIENTLY TO RESIST ANY
MOTION DURING SPRING APPLICATION AND DOOR TRAVEL. IF BACK
HANGS PIVOT OR DEFLECT, ADD REINFORCEMENT UNTIL THEY REMAIN
FIRM AND STATIONARY. ANY BACK HANG THAT HAS BENT MUST BE
REPLACED.
WARNING
KEEP HORIZONTAL TRACKS PARALLEL AND WITHIN 3/4” TO 7/8” FROM
DOOR EDGE, OTHERWISE DOOR COULD FALL, RESULTING IN SEVERE OR
FATAL INJURY.
IMPORTANT:
DO NOT SUPPORT THE WEIGHT OF THE DOOR ON ANY PART OF THE REAR
BACK HANGS THAT CANTILEVERS 4” OR MORE BEYOND A SOUND FRAMING MEMBER.
NOTE:
If rear back hangs are to be installed over drywall, use (2) 5/16” x 2” hex head lag
screws and make sure lag screws engage into solid structural lumber.
WARNING
FAILURE TO ASSEMBLE AND ATTACH REAR BACK HANGS PROPERLY
ACCORDING TO THE ABOVE INSTRUCTIONS MAY RESULT IN DOOR
FALLING WHEN RAISED, CAUSING SEVERE OR FATAL INJURY.
NOTE:
Perforated angle must be attached to sound framing members and
nails should not
be used
