INSTALLATION STEP 1
Determine the Header Bracket
Location
Installation procedures vary according to garage door
types. Follow the instructions which apply to your
door.
If your door is a canopy or dual-track style garage
door, a door arm conversion kit is REQUIRED.
Follow the installation instructions included with the
replacement door arm sectional.
SECTIONAL DOOR
AND ONE-PIECE DOOR WITH TRACK
1. Close the door and mark the inside vertical
centerline of the garage door.
2. Extend the line onto the header wall above the
door.
You can fasten the header bracket within 1.2 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 17) when clearance is minimal. (It may be
mounted on the wall upside down if necessary,
to gain approximately 1 cm.)
If you need to install the header bracket on a
38 mm board (on wall or ceiling), use lag screws
(not provided) to securely fasten the 38 mm board
to structural supports as shown here and on
page 17.
3. Open your door to the highest point of travel as
shown. Draw an intersecting horizontal line on the
header wall 5 cm above the high point. This height
will provide travel clearance for the top edge of the
door.
Proceed to Step 2, page 18.
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 38 mm board 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.
