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

STEP 1 Determine theHeader 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 16) 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 16.
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:
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 16 for
ceiling installation.
