Installation
STEP 1 Determine the header bracket location
To preventpossible SERIOUS INJURY or DEATH:
l Header bracketMUST be RIGIDLY fastened to structural support on header wall or ceiling,
otherwise garage door mightNOTreverse when required.DO NOT install header bracketover
drywall.
l Concrete anchors MUST be used if mounting header bracket or 2x4 into masonry.
l NEVER try to loosen, move or adjustgarage door, springs, cables,pulleys,brackets,or their
hardware,ALL ofwhich are under EXTREME tension.
l ALWAYS call a trained door systems technician ifgarage door binds,sticks, or is out of balance.
An unbalanced garage door mightNOT reverse when required.
Installation proceduresvary according to garage door types.Follow the instructionswhich applyto your
door.
1. Close the door and mark the inside vertical centerline ofthe 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) ofthe leftor right ofthe door center only ifa torsion spring or center bearing
plate is in the way; or you can attach it to the ceiling (see page 13) 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 securelyfasten the 2x4 to structural supports asshown here and on page 13.
3. Open your door to the highestpointof travel asshown. Draw an intersecting horizontal line on
the header wall 2" (5 cm) above the high point:
l 2" (5 cm) above the high pointfor sectional door and one-piece door with track.
l 8" (20 cm) above the high point for one-piece door without track.
Thisheightwill provide travel clearance for the top edge ofthe door.NOTE: If the total number ofinches
exceeds the height available in your garage, use the maximum height possible, or refer to page 13 for
ceiling installation.
