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 inter secting 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.
