Things to Know Before You Begin
YOU MUST HAVE COMPLETED THE
MANUFACTURER’S VERTISTACK DOOR INSTALLATION
TRANING AND BE CERTIFIED BEFORE ANY
INSTALLATION IS ATTEMPTED. Carefully read these
instructions in their entirety before starting installation of the
door. Becoming familiar with the components before
assembling the door will help reduce installation time.
Springs and related hardware are under EXTREME
tension and could cause SEVERE INJURY OR DEATH
if mishandled. DO NOT ATTEMPT TO REPAIR OR
ADJUST the springs, red fasteners, hardware or
structure to which they are attached.
To ensure smooth operation, it is recommended to install
and operate the door in a temperature-controlled
environment. Operating the door in freezing
temperatures, without interior temperature regulation,
may inhibit smooth operation.
Before Starting Installation:
 Check the opening size and verify that the door is
the proper size for the opening. As standard, door
sections are 6” wider than the opening regardless of
jamb type. No stop moldings are required in this
application. The opening must be plumb and
square to assure a good fit.
 Check all materials with the hardware box and
spring box labels to ensure you have all the correct
parts, both in number and type. Any report of
shortages must be accompanied by the contract
number. Report the number of pieces received
along with the number of pieces short. Springing
information, including the number of turns to wind
spring, can be found on the hardware box label.
 Check for sufficient headroom and side room.
Headroom is the distance between the top of
opening to the ceiling or the lowest obstruction.
 The hardware package supplied with your door
should include red fasteners for attachment of the
torsion spring center bracket and other
components or assemblies under tension. These
fasteners must be securely attached as indicated
in the installation manual.

2. Note should be verified by driver’s signature.
3. Notify both carrier and manufacturer.
Checking and Preparing the Opening
1. Check the floor to ensure it is level. If necessary, shim the area where the wall angle and track will sit
on the floor.
a. This step is critical to getting the shaft level later on in the installation.
b. If the floor is more than 1/4” [6 mm] per 10 feet [3048 mm] of width out of level, stop and consult
factory.
2. Check the width of the opening.
a. If the opening is ¼” or more than the measurement stated on the shop drawings, add material to
the inside of the jambs so the wall angles do not protrude into the opening.
b. If the opening is less than the measurement stated on the shop drawings, split the difference at
both jambs and place a mark at this location. Be sure there is adequate structure to fasten to at
this location.
3. Check the opening height.
a. If the opening height is greater than the measurement stated on the shop drawings, material will
need to be added to the underside of the lintel to ensure the door seals properly when fully
closed.
4. Check the area above and to the sides of the opening to ensure there are no obstacles that will be in the
way of the installation (such as ductwork, heaters, water/gas/electrical conduit, etc.).
Installing the Right-Hand Wall Angle, Track, and Brackets
5. Locate lower wall angle and track assemblies. See Figure 1 & 2 to identify right-hand and left-hand
lower wall angles. Note that the track extends above the wall angle at the top.
Figure 1 - TOP OF RIGHT-HAND LOWER WALL ANGLE ASSEMBLY

11
Figure 2 - BOTTOM OF RIGHT-HAND LOWER WALL ANGLE ASSEMBLY
6. Disassemble track from the right-hand lower wall angle and set track aside.
(Note: The lower wall angle cannot be installed properly without removing the track first).
7. Place lower wall angle on the floor (shim if needed) against the jamb, holding the small flange of the
wall angle flush with the inside of the jamb.
I. If the opening is less than the measurement stated on the shop drawings, set the lower wall
angles back from the jamb an equal distance on both left and right-hand sides so that the
distance between them is equal to the opening stated on the shop drawing.
II. Be sure there is adequate structure per shop drawing requirements to fasten to at this location.
8. Locate the wall fasteners in the hardware box.
9. Fasten the right-hand lower wall angle to the wall. Predrill holes if attaching to steel or concrete.
10. Locate the right-hand upper wall angle assembly, see Figure 3.
Figure 3 - RIGHT HAND UPPER WALL ANGLE ASSEMBLY
11. Place the right-hand upper wall angle assembly on top of the lower wall angle and against the jamb,
holding it in line with the lower wall angle assembly.
12. Ensure both lower and upper wall angles are plumb.

12
13. Fasten the upper wall angle assembly to the wall using the supplied fasteners. Mark and predrill
holes if desired.
14. Attach sensor to upper wall angle, referring to Figure 4 for placement:
a. Locate sensor mounting studs.
b. Ensure lens on sensor is pointing OUTWARDS from inside of wall angle.
c. Attach sensor to studs and install nuts to fasten sensor.

wall angle assembly using the 3/8 x 1” [9 mm x 25 mm] carriage bolts, washers, and nuts provided in
the hardware box. See Figure 7.
a. Note: Nuts go on the outside of the bracket.
Figure 7 – RIGHT-HAND BRACKET ASSEMBLY MOUNTED TO UPPER WALL ANGLE ASSEMBLY
16. Locate the wiring harness extensions for both of the sensors. The ends without the connectors will
be fed behind the ramp.
17. As the bracket is being installed, run both sensor wiring harness extensions through grommet hole in
bracket displayed in Figure 6.
18. Wires will then hang free until future steps.
19. Fasten the bracket assembly to the wall through the flange in the bracket using the appropriate
hardware. See Figure 8. Note: If your door includes a side-mounted operator, do not install fastener
in operator mount location until operator installation.

Figure 8 - RIGHT HAND BRACKET ASSEMBLY WITH WALL FASTENERS
20. Attach the lower track piece, removed in step 6, to the wall angle using 1/4" x 5/8" [6 mm x 16 mm]
track bolts and nuts. Making sure to also install the additional track bolt in the top of the track through
the top wall angle. The upper removable track piece will not be installed at this time to allow for
loading of sections later on.
Figure 9 – RIGHT-HAND WALL ANGLE, TRACK, AND BRACKET ASSEMBLY
NOTE: In order to ensure the correct spacing between the right and left-hand wall angles, the
Header Seal Cross Member is used as an installation tool to SET the spacing between wall
angles.

15
Installing the Left-Hand Wall Angle, Track, and Brackets
Figure 10 – Header Seal Cross Member
21. Locate the header seal cross member. This will be used to set the spacing of the left-hand lower wall
angle.
22. Measure the length of the header seal cross member from notched face to notched face and confirm
it equals the opening width dimension listed on the shop sheet.
23. Referring to Figure 10 and Figure 11, place the header seal cross member across the opening with
the larger flange resting on the ground. The right-hand wall angle spacing notch will go over the
smaller flange on the right-hand lower wall angle.
24. Ensure the header seal cross member is level across the opening.
Figure 11 - HEADER SEAL CROSS MEMBER INSTALLATION SPACER
25. Disassemble the left-hand track from the lower wall angle.

16
26. Plumb the left-hand wall angle against the wall. The short flange of the wall angle should be flush
with the jamb or on the mark placed on the jamb if the opening width was less than stated on the
shop drawings, see step 2.
27. Use the header seal cross member to verify the proper spacing for the left-hand wall angle. Place
short flange on left-hand wall angle inside of left-hand wall angle spacing notch, mirroring Figure 11.
28. Use header seal cross member to ensure equal spacing between wall angles over opening height.
29. If the distance between the wall angles is correct, repeat steps 5 through 20 for the left side of the
opening, leaving out the upper removable track piece. This will allow the loading of the sections later
on.
Installing Track Rollers, Strap and Loading Bottom Section
30. Locate the bottom door section. It could be differentiated from the other sections by referencing the
bottom inserts (bottom left and right corner). The bottom section will have the strap bottom inserts
which differ from any other section. Place it on sawhorses or other supports.
31. If a sensing edge option has been selected, slide the sensing edge on to the bottom retainer, making
sure the sensing edge wire lead is oriented toward the same side of the door as the operator
mounting position.
32. Install the track rollers, making sure to slide an axle spacer on each of the track roller axles before
inserting the track rollers into the end stiles of each section. For larger doors, a heavy-duty white
track roller will be supplied. This roller is installed toward the bottom of the section, nearest the strap
bottom insert.
Figure 12 - BOTTOM SECTION WITH RIGHT-HAND END STILE DETAIL.
IMPORTANT: Insert the track rollers into end stiles, there are two per side of the section. Be
sure to place the axle spacers over the track roller axles before inserting the track rollers into
the end stiles.

17
Figure 13 - AXLE SPACER
33. Remove the cotter pin in order to remove the strap pin shown in Figure 14.
34. Attach the straps to the bottom section.
a. Place the loop of the strap, without tag and with the fold over side facing the door, in the bottom
insert assembly.
b. Re-Insert the strap pin in the existing location followed by the cotter pin. Once the cotter pin is in
place, bend one leg over the pin.
I. If the door includes the safety brake safety system option as shown in Figure 15, as the strap
becomes tight the stop mechanism will rotate into the bottom insert assembly and out of the way
of operation. If the strap becomes loose, due to failure or other reasons, the stop mechanism
will deploy and catch the toothed angle installed on the wall angle.
Figure 14 - ATTACHING STRAP TO BOTTOM SECTION
Figure 15 – ATTACHING SAFETY BRAKE SAFETY SYSTEM TO BOTTOM SECTION with the STOP
BRACKET ASSEMBLY

18
35. Place the bottom section into the opening down through the vertical track, as seen in Figure 16, and
place section on floor.
Figure 16 - RIGHT-HAND TRACK AND TRACK ROLLER SPACING
36. If the floor is out of level, shim the bottom section to make it level at this time.
Installing the Shaft assembly, Spools, and Straps
37. Prior to installing the shaft assembly, ensure that there is adequate structure - noted as the spring
pad on the shop drawing - for spring anchor brackets located near the center of the shaft, above the
opening, and (if required) for additional shaft support brackets. See shop drawing for location of the
spring pads.
Each spring anchor bracket requires a wood/steel spring pad. Spring pads and hardware are not
supplied. You must make sure that the wood or steel spring pad is of good quality and free of
cracks or splits. (Note: A single spring pad could be used to mount up to two spring anchor
brackets). Failure to provide the necessary spring pad could result in the sudden release of
spring forces with dangerous force and severe injury.
IMPORTANT: The wood spring pad must be made of a Grade 2 or better southern yellow pine
(also known as southern pine or yellow pine) 2" x 6" x 12" [51mm x 152 mm x 305 mm]
minimum. The southern yellow pine must be free of splits and cracks. Do not use wood labeled
as spruce-pine-fir (or SPF). Use of SPF or other non-approved material could result in the
sudden release of spring forces with dangerous force and severe injury.
Steel spring pads should be 1/4" x 10" x 12" [6 mm x 254 mm x 305 mm] minimum, securely
fastened to the structure.
The wood/steel spring pad must be installed into the structural frame of the building, not
on/over drywall or sheet rock. Use at least (4) 3/8" x 3" [10 mm x 76 mm] long lag screws (not
supplied) for wood structures or 3/8" [10 mm] masonry anchors (not supplied) for
concrete/block structures (one at each corner). Do not install lag screws/masonry anchors less
than 1-1/2" [38 mm] from the sides or ends of the spring pad. Under no circumstances should
the spring pad be attached with nails. FAILURE TO SECURE THE SPRING PAD TO THE
STRUCTURAL FRAME OF THE BUILDING WITH THE REQUIRED TYPE AND NUMBER OF LAG
SCREWS/MASONRY ANCHORS COULD RESULT IN THE SUDDEN RELEASE OF SPRING
FORCES WITH DANGEROUS FORCE AND SEVERE INJURY.

a. Additional bearings and anchor brackets may be required and as designated on the shop
drawing. If so, they must be assembled to the shaft before the spools, as shown in Figure 18.
i. Note: Verify requirements on shop drawing.
b. If the configuration requires a split shaft, install half of shaft coupler on each shaft. Install shaft
key before tightening set screws. Note: Do not exceed ½ turn after coming in contact with the
shaft.
43. Fasten spring anchor bracket to spring pad using:
a. Wood structure: 5/16" x 1-5/8" [8 mm x 41 mm] RED-COLORED lag screws.
b. Steel structure: 5/16" x 1" [8 mm x 25 mm] RED-COLORED self-tapping screws.
44. Center shaft(s) in opening and rest the shaft(s) on the brackets, oriented as shown in Figure 18.
Slide spring anchor cone/center bearing against spring anchor bracket and attach loosely using (2
each) 3/8" x 1-1/2" [10 mm x 38 mm] cap screws and nuts. Fasten shaft couplers (if necessary)
together while making sure to keep the keys aligned.
45. Make sure the shaft protrudes past the bracket on the side of the operator by at least 3.00” to allow
for installation of the sprocket. Note: If necessary, excess shaft material could be cut and removed.
46. Fasten shaft bearings to brackets using (4 each) 3/8” x 1-1/4” [10 mm x 32 mm] bolts & nuts.
47. Tighten spring anchor cone/center bearing fasteners to spring anchor bracket.
