Warning
If the header bracket is not rigidly fastened to a sound
structural support on the header wall or ceiling, the
safety reverse system may not work and could cause
serious injury or death. DO NOT move or adjust springs
or garage door hardware, as these parts are under
extreme tension and could cause injury or death.
8. INSTALLATION STEPS
Identify a sound structural support on header wall above garage door for header bracket mounting (see Fig. 10). If appropriate header does not
exist, replace or install a new support using a 2x4 or 2x6 board. Fasten it securely using lag screws (not provided) to structural supports of garage.
8-1. MEASURE AND MARK DOOR AREA
Before starting your installation, the door and the header above the door
must be measured and marked. This way, the appropriate brackets can be
mounted at the correct locations avoiding installation and operating
difficulties later.
MARK VERTICAL CENTER LINE:
• Measure door width, then locate the center point (see Fig. 9).
• Mark a vertical line on the upper half of your door, on the top edge of your
door, and on the header, through the center point.
MEASURE DOOR’S HIGHEST TRAVEL POINT:
(Review Figs. on p. 5 for details)
• Open door to its highest travel point and measure from the garage floor
to the top of door.
• Write down this distance.
• Add 1-1/4” to the door travel height (measured above).
MARK HORIZONTAL LINE FOR HEADER BRACKET LOCATION:
• Close door and measure the required distance (determined above) from
the garage floor to the header.
• Mark a horizontal line, intersecting the vertical center line, on header.
This is the position at which the bottom of the header bracket should
be installed.
• In case of minimal clearance above the door, the header bracket may be
mounted to the ceiling. In this case, extend the vertical center line onto
the ceiling, and mark a horizontalline on the ceiling no further than 4”
from the header wall. The header bracket should be mounted no farther
than this distance from the header wall.
