Header Bracket Positioning
The header bracket must be rigidly fastened
to a structural support of the garage. Reinforce
the wall or ceiling with a 40 mm (1-1/2") board if
necessary. Failure to comply may result in
improper operation of safety reverse system.
You can attach the header bracket either to the
header wall (1) or to the ceiling (3). Follow the
instructions which will work best for your particular
requirements.
With the door closed, mark the vertical centerline (2)
of the garage door. Extend line onto header wall
above the door.
Open door to highest point of travel. Draw an
intersecting horizontal line (4) on header wall 5 cm
(2") above high point to provide travel clearance for
top edge of door.
