STEP 1 Determine the header bracket location
To prevent possible SERIOUS INJURY or DEATH:
l Header bracketMUST be RIGIDLY fastened to structural support on header wall or ceiling,
otherwise garage door mightNOTreversewhen required.DO NOT install header bracketover
drywall.
l Concreteanchors MUSTbe used if mounting headerbracketor2x4 into masonry.
l NEVER trytoloosen,moveor adjust garage door, springs, cables,pulleys,brackets,ortheir
hardware, ALL of which are underEXTREMEtension.
l ALWAYS call a trained door systemstechnician if garagedoor binds, sticks,or is out of balance.
An unbalanced garage door might NOT reverse when required.
Installation procedures vary according to garage door types.Followtheinstructions which apply to your
door.
1. Closethedoor and mark the inside vertical centerline of the garagedoor.
2. Extend the line onto the header wall above the door.You can fasten the header bracketwithin 4
feet(1.22 m) of the leftor right of the doorcenter onlyifa torsion spring or center bearing plate is
in the way; or you can attach it to the ceiling (see page 11) when clearance is minimal. (Itmaybe
mounted on the wall upside down if necessary, to gain approximately 1/2" (1 cm).Ifyou need to
install the header bracketon a 2x4 (onwall or ceiling), use lag screws(notprovided) to securely
fasten the 2x4 to structural supports as shown here andon page 11.
3. Open your door tothe highest point of travel as shown.Drawan 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 pointfor one-piece door without track.
Thisheight will provide travel clearance for the top edge of the door. NOTE: If the total number ofinches
exceeds the height available in your garage, use the maximum heightpossible, or refer to page 11 for
ceiling installation.

line as shown (with the arrowpointing toward the ceiling).
2. Markthe vertical set of bracketholes.Drill3/16" pilot holes and fasten the bracket securelyto a
structural support with the hardware provided.
OPTION B CEILING INSTALLATION
1. Extend the verticalcenterline onto the ceiling as shown.
2. Centerthe bracketon the verticalmark,no more than 6"(15cm) from the wall. Makesure the
arrow is pointing away fromthewall.The bracket can be mounted flush against the ceiling when
