INSTALLATION STEP 1

Determine the Header Bracket
Location

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.

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.
