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. DO NOT
install header bracket over drywall.
•
Concrete anchors MUST be used if
mounting header bracket or 2x4 into
masonry.
•
NEVER try to loosen, move or adjust
garage door, springs, cables, pulleys,
brackets, or their hardware, ALL of which
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.

Determine the header bracket location
NOTE: If you are installing the garage door opener on a one-piece door, visit www.raynor.com for
installation instructions.
1.1
Close the door and mark the inside vertical centerline of the garage door.
1.2
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.
1.3
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. This height will provide travel clearance for the
top edge of the door.
NOTE: If the total number of inches exceeds the height available in your garage, use the maximum
height possible, or refer to page 8 for ceiling installation.
