STEP

Determinethe HeaderBracketLocation
To prevent possible SERIOUSINJURY or DEATH:
• Headerbracket MUST be rigidly fastened to structural
support on header wall or ceiling, otherwise garage door
might NOT reverse when required. DONOT install header
bracket over drywall.
• Concreteanchors MUSTbe used if mounting header bracket
or 2x4 into masonry.
• NEVERtry to loosen, move or adjust garage door, springs,
cables, pulleys, brackets, or their hardware, ALL of which are
under EXTREMEtension.
• 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.
nstallation procedures vary according to garage door types.
Follow the instructions which apply to 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 fastenthe headerbracket within 4 feet (1.22 m) of
the left or right of the doorcenter onlyif a torsionspring 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
mountedon the wall upside downif necessary,to gain
approximately1/2" (13 ram).
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 as shown here and on page 13.
3. Openyour door to the highest point of travel as shown. Draw an
intersecting horizontal line on the header wall abovethe high
point:
• 2" (5 cm) abovethe high point for sectional door and one-
piece door with track.
• 8" (20 cm) abovethe high point for one-piece door without
track.
This height will provide travel clearancefor the top edge of the
door.
NOTE:If the total number of inches exceedsthe height availablein
your garage, use the maximum height possible, or refer to page 13
for ceiling installation.
