Mid-America Door
Residential Garage Door Installation Manual
Read all instructions carefully before beginning installation. Reading and following these
instructions will help assure proper installation and operation of your garage door.
Garage doors use torsion or extension springs to counter balance the weight of the door.
Never under any circumstances attempt to remove or install any spring assembly, bottom
fixtures, spring anchor, or any other component under spring tension. Contact a
professional for help. Failure to do so could result in serious injury or death.

IMPORTANT SAFETY INFORMATION
•
Garage doors use springs to counterbalance the weight of the door. Never under
any circumstance attempt to remove or install any spring assembly, bottom
fixtures, spring anchors, or any other component under spring tension. Contact a
professional for help. Failure to do so could result in personal injury or death.
•
Never under any circumstances attempt to adjust, repair, or tighten torsion or
extension springs, cables, pulleys, bottom fixtures, or any other parts that are
under spring tension. Only a professional installer should adjust or tighten the
bottom fixtures, spring assemblies, or cables.
•
When installing a door with torsion springs use only ½” x 18” constant diameter
cold rolled steel winding bars. Do not use screwdriver, ratchet handles, wrenches,
or any other substitutes. See page 11 for more details.
•
The spring anchor on a torsion spring door must be mounted to a surface capable
of withstanding the torque of the spring assembly. To keep the wood from
splitting, a 3/16” pilot hole must be pre drilled. See page 11 for details.
•
The sway brace must be installed on the rear track hanger. Failure to do so could
allow the track to move and the door to fall, which could result in serious injury
or death. See page 8 for more details.
•
When door is operating keep hands and finger away from sectional joints. For
manual operation of the door, always use the lifting points as described on page 7
of the installation manual.
•
If the door has an electric opener then the top section must have a strut mounted
above the top fixture see page 9 for details.
•
Garage doors are not toys, do not let children operate or play around the door.
•
Never operate a door with bent, loose, or broken parts. Contact a professional for
service.

Things To Remember
•
•
•
•
•
Allow enough time to finish the installation (at least 4 hours).
Use care in lifting or handling door sections. They are made of steel and can be heavy.
If replacing an existing door the entire door, including the track, and all components, must be
replaced.
Use caution when installing screws. If over tightened the sheet metal will “strip out”.
When installing a door with torsion springs always use ½” x 18” constant diameter cold rolled
steel bars. Never use screwdrivers or any other substitutes.
Important Safety Information
Overhead doors are heavy. Many of the components are under extreme tension and can
exert strong forces. Improper use, installation, or maintenance of the door could lead to
severe injury or death. By adhering to the precautions given throughout this manual, this
door should provide many years of safe and reliable operations.
•
•
•
•
Doors with electric openers must have the top section reinforced to avoid damage to the top section.
Keep door in full view and free of obstructions while operating door.
Do not allow children to operate the door, including any electrical components.
Do not stand under door or walk through the doorway while door is moving.

!!!! Warning !!!!
Only professionally trained installers should install and maintain doors
and components.
HARDWARE COMPONENTS
Make sure that all components are accounted for. It is recommended that the hardware and components be
separated into piles on the garage floor for ease of locating during the installation process.
The following chart (Table 1) is provided only as a general reference. Each door depending upon size and
installation specifications may or may not have all of the components shown.

Step 1
First Obstruction
Measure The Door Opening
•
•
Headroom
First, measure the door opening. It should be
approximately the same size as the door itself (see
figure 1).
Next measure the headroom. The headroom is the
amount of room from the top of the opening to
ceiling or lowest obstruction (see figure 1).
As a general rule:
12” radius track requires 12” of headroom.
15” radius requires 15”of head room.
Door Height
NOTE: If you do not have the required headroom space,
contact your local dealer for low headroom options.

Locate the section with the black weather seal and
place it in the opening, with the weather seal down.
Check and make sure that the section is level. If it is
not level you may need to shim the bottom.
Hammer a nail into the jamb on each side of the end
stiles and bend the nail head over the end stiles in
order to hold the section in place (figure 2).
Attach a bottom fixture to each end stile using ¼ x ¾
Zip screws (figure 2).
Attach the # 1 hinges to the center and end stiles
using ¼ x ¾ Zip screws (figure 2). For ease of
installation the hinges are stamped with a number and
an arrow that indicates the orientation that the hinge
should be installed.

Night latch Assembly
For doors 9’ or less, the center stile is most likely the location of the lock. However, if the door is wider than 9’ or has more than one
center stile then the correct placement of the lock is one stile to the left of the right end stile.
•
On the selected stile of the second section, punch out both the small and large hole. Using the hole in the stile as a guide,
drill a pilot hole through the face of the pan with the small bit on a 1- ¼ hole saw bit.
•
With the center of the hole marked on the face of the pan, drill the 1- ¼ hole from the outside of the pan to the inside.
•
For the ¾ “ hole repeat the same process, using a ¾” hole saw bit, however, on the ¾ “ hole the two small holes above and
below must also be drilled out using a 1/8 “ bit. Attach lock as shown in (figure 4).
•
If the key lock assembly is used then it will serve as a lift point and the handle is not required or included. The key lock must
be installed according to the key lock installation instructions see (figure 4).

Step 4
Installing The Handle & Step Plate
The normal location of the handle is one stile to the right or left of either end stile. If the door only has one center stile then mount the
handle directly above the hinge (see Figure 5). Place the inside handle vertically on the desired center stile. Using the template or by
holding the handle flat against the stile, mark the location of the holes using a scribe or small drill bit (template on last page of this
manual).
• Check and make sure that the holes are centered on the stile.
• With the handle location marked drill a ¼” hole from the inside of the door through the stile and face of the section, making
sure that the drill bit is square with the section. From the outside of the door drill out the two ¼” holes to ½” holes. Only
drill the ½” hole through the face of the section, leave the ¼” hole in the stile.
• Slide the outside handle through the face of the section and attach the inside handle to the outside handle by using two #10 x
3½” long screws (see Figure 6).
• Do not over tighten screws.
• Next, the step plate should be attached on the outside and inside of the first section, at the bottom, by using a two Tek screws
on each side of the door. Make sure that the Tek screw goes through the stile on the front and back of the door.
Note:
In compliance with ANSI / DASMA 116/2000 two lift points must be on the inside and outside of the door. A lift
point can be a lock handle, stationary handle, or step plate. The step plate should be mounted on the outside and inside
within 6 inches from the bottom of the first section on the stile directly below the handle or key lock assembly. If the stationary handle
is used then it must be mounted vertically on the outside and inside of the door within 30 inches of the step plate on the second
section. If a lock handle is used then it must be mounted according to the instructions on page 6.

Installing The Remaining Sections
•
•
Attach the remaining sections in the same manner as
the first section. For all center or intermediate stiles,
attach #1 hinges. For the end stiles on the top of the
second section use # 2 hinges. For the end stiles on
the third section use # 3 hinges. If your door has
more than four sections then use the hinge that
corresponds with your section on the end stiles (see
figure 7).
On the top of the last section attach the adjustable top
fixture to the end stiles using four ¼ x ¾ tek screws
(see figure 7).

Make sure that the track is level and square by using
diagonal measurements. Attach the horizontal track
to the vertical track using a ¼ track bolt with a ¼ nut
and using a 3/8 x 1 ½ carriage head bolt with a 3/8
hex head nut attach the horizontal angle to the
vertical angle (see figure 8).
Install the angle back hanger (provided by the
installer) to the rear of the horizontal track. Make
sure that the track is level and square, by using
diagonal measurements (see figure 9a). The back
hanger must be firmly attached to the building
structure and be capable of withstanding the weight
of the door.
Loosen the top fixture and adjust the door so that it is
sealed against the door jamb and tighten the bolts
(see figure 9b).
