INSTALLATION STEP 1Determine the Header Bracket Location

WARNING

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 2x4 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.

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
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 9) when clearance is minimal. (It may be
mounted on the wall upside down if necessary,
to gain approximately 1/2".)
