Installation Step 1
Determine the Header Bracket Location
Installation procedures vary according to garage door types.
Follow the instructions which apply to your door.
Close the door and mark the inside vertical centerline of the 1.
garage door.
Extend the line onto the header wall above the door. 2.
You can fasten the header bracket within 4 feet
(1.22 m) of the left or right of the door center only if a
torsion spring or center bearing plate is in the way; or you
can attach it to the ceiling (see page 9) when clearance is
minimal. (It may be mounted on the wall upside down if
necessary, to gain approximately 1/2" (1 cm).
If you need to install the header bracket on a 2x4 (on wall or
ceiling), use lag screws (not provided) to securely fasten the
2x4 to structural supports as shown here and on page 8.
Open your door to the highest point of travel as shown. Draw 3.
an inter secting horizontal line on the header wall above the
high point:
3" (7.5 cm) above the high point for sectional door and one- •
piece door with track.
8" (20 cm) above the high point for one-piece door without •
track.
This height will provide travel clearance for the top edge of the
door.
NOTE: If the total number of inches exceeds the height
available in your garage, use the maximum height possible, or
refer to page 9 for ceiling installation.
To prevent possible serious injury or death:
Header bracket • MUST be RIGIDLY fastened to structural
support on header wall or ceiling, otherwise garage door
might not reverse when required. DO NOT install header
bracket over drywall.
Concrete anchors
• MUST be used if mounting header bracket
or 2x4 into masonry.
NEVER
• try to loosen, move or adjust garage door, springs,
cables, pulleys, brackets, or their hardware, ALL of which
are under EXTREME tension.
ALWAYS
• call a trained door systems technician if garage
door binds, sticks, or is out of balance. An unbalanced
garage door might not reverse when required.
