Add a 2x4 as a Structural Support
(If Necessary)
Determine the Highest Point of
Travel, and Draw Horizontal Line
for Header Bracket Placement
NOTE: You can fasten the header bracket within 4 feet
(1.2 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 when clearance is
minimal.
Fasten header bracket securely to structural supports.
It may be necessary to use a 2x4 as a structural
support if installing on drywall or between two studs
as shown in Step 3. Securely fasten 2x4 to structural
supports using lag screws (not provided). Concrete
anchors must be used if mounting header bracket or
2x4 into masonry.
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.
• NEVER try to loosen, move or adjust garage door,
springs, cables, pulleys, brackets, or their hardware,
ALL of which are under EXTREME tension.
INSTALL THE HEADER BRACKET
Mark the center of the garage door on
door and wall and extend onto the ceiling
Mark a spot on the “center of the garage door”
line, 2" (5 cm) above the highest point of travel
of the garage door.
In some installations it may be necessary
to install a 2x4 across two studs to create a
location for header bracket or over drywall.
Use lag screws (not provided) to secure 2x4
(structural support) into wood. Use concrete
anchors to secure 2x4 into masonry.
