Supports
If the header bracket is not rigidly fastened to
a structural support on the header wall or
ceiling, the safety reverse system may not
work properly (see page 26). The door might
not reverse when required, and could cause
serious injury or death.
The garage door springs, cables, pulleys,
brackets and their hardware are under extreme
tension. Do not attempt to loosen, move or
adjust them yourself. Serious personal injury
or death could resulL Call for professional
garage door service.
• Close the door and mark the inside
vertical centerline of the garage door.
• Extend the line onto the header wall
above the door.
Remember, you can fasten the
header bracket within 2 feet to 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 (refer to page 12)
when clearance is minimal. (It may
be mounted on the wall upside down
if necessary, to gain approximately
1/2".)
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 structuralsupports as shown
here.
• Open your door to the highest
point of travel as shown. Draw
an intersecting horizontal line on
the header wall 2" above the
high point. This height will
provide travel clearance for the
top edge of the door.
Door clearance brackets are
available when headroom
clearance is less than 2".
