INSTALLATION STEP 1
Determine the Header Bracket
Location
To prevent possibleSERIOUSINJURYor DEATH:
• HeaderbracketMUST be RIGIDLYfastened to structural
support on headerwall or ceiling, otherwise garagedoor
might not reversewhen required. DONOTinstall header
bracket overdrywall.
• Concreteanchors MUSTbe usedif mounting header
bracket or 2x4 into masonry.
• NEVERtry to loosen, move or adjust garagedoor, 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 not reversewhen required.
Installation procedures vary according to garage door
types. Follow the instructions which apply to your door.
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 4 feet
(1.22 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 13) when clearance is minimal. (It may be
mounted on the wall upside down if necessary, to
gain approximately 1/2" (1 cm).)
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 structural supports as
shown here and on page 13.
3. Open your door to the highest point of travel as shown.
Draw an intersecting horizontal line on the header wall
above the 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 clearance for the top
edge of the door.
NOTE: If the total number of inches exceeds the
height available in your garage, use the maximum
height possible, or refer to page 13 for ceiling
installation.
