Identify a sound structural support on header wall above garage
door for header bracket mounting. See Fig. 11. If appropriate
header does not exist, replace or install a new support using a 2x4
(50mm x 100mm) or a 2x6 (50mm x 150mm) board. Fasten it securely
using lag screws (not provided) to structural supports of garage.
Before starting your installation, the door and the header above
the door must be measured and marked. This way, the appropri-
ate 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 (Fig. 10).
 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. 4 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" (30mm) 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 horizontal
line on the ceiling no further than 4" (100mm) from the
header wall. The header bracket should be mounted no
farther than this distance from the header wall.

 Position door bracket along vertical center line of
door with pin hole facing top of the door and top edge of
the bracket 4” to 5” (100 - 125mm) below top edge of the
door, or roughly at the same height as top rollers on the door.
 Mark locations of securement holes through door bracket.
 Drill two 1/4" holes through door for securement of door bracket.
 Insert carriage bolts (1/4” x 2”) from the outside through door and
bracket, then secure with lock washers and nuts from the inside.
 Tighten nuts firmly.
