Installation
STEP 1 Determine the header bracket location
To prevent possible SERIOUS INJURY or DEATH:
• Header bracket MUST be RIGIDLY fastened to structural supporton 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 bracketor 2x4 into masonry.
• NEVER try to loosen, move or adjust garage door, springs, cables, pulleys, brackets, or their
hardware,ALL ofwhich 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.
Installation procedures vary according to garage door types. Follow the instructionswhich applyto 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 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.
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:
l2" (5 cm) above the high pointfor sectional door and one-piece door with track.
l8" (20 cm) above the high pointfor one-piece door without track.
This heightwill provide travel clearance for the top edge ofthe door.NOTE:If the total number of inches
exceeds the height available in your garage, use the maximum height possible, or refer to page 12 for
ceiling installation.
