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.

Installation procedures vary according to garage door types. Follow the instructions which apply to your door.

SECTIONAL DOORAND ONE-PIECE DOOR WITH TRACK

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 10) 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 10.

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

shown. Draw an intersecting horizontal line on the
