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

(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 9) when clearance is minimal. (It may

be mounted on the wall upside down if

necessary, to gain approximately 1/2"[1.27 cm].)

Structural Supports

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 9.

3. Open your door to the highest point of travel as

shown. Draw an intersecting horizontal line on the

header wall 2" (5 cm) above the high point. This

height will provide travel clearance for the top edge

of the door.

Proceed to Step 2, page 9.
