INSTALLATION STEP 1
Determine the Header Bracket Location
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.
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 18) 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.
