To prevent possible SERIOUSINJURYor DEATH:
• Header bracket MUST be RIGIDLYfastened to structural
support on headerwall or ceiling, otherwise garagedoor
might NOTreverse when required. DO NOTinstall header
bracket over drywall.
• Concrete anchors MUST be used if mounting headerbracket
or 2x4 into masonry.
• NEVERtry to loosen, move or adjust garage door, springs,
cables, pulleys, brackets, or their hardware, ALL of which are
under EXTREMEtension.
• ALWAYScall a trained door systems technician if garage
door binds, sticks, or is out of balance.An unbalanced
garagedoor might NOTreverse when required.
Installation procedures vary according to garage door types.
Follow the instructions which apply to your door.
1. Closethe door and mark the inside vertical centerline of the
garagedoor.
2. Extendthe line onto the headerwall above the door.
Youcan fastenthe header bracketwithin4 feet (1.22 m) of
the left or rightof the door centeronly if a torsionspringor
centerbearing plate is in the way;or you can attach it to the
ceiling (see page 13) whenclearance is minimal. (It may
be mountedonthe wall upsidedownif necessary,to gain
approximately1/2" (1 cm).)
Ifyou needto install the header bracket on a 2x4 (on wall or
ceiling), use lag screws (not provided) to securely fasten the
2x4 to structural supports as shown here and on page 13.
3. Openyour door to the highest point of travel as shown. Draw
an intersecting horizontal line on the headerwall abovethe high
point:
• 2" (5 cm) above the high point for sectional door and
one-piece door with track.
• 8" (20 cm) above the high point for one-piece door without
track.
This height will provide travel clearancefor the top edge of
the door.
