• Close the door and mark the inside
vertical centerline of your garage door.
Extend the line onto the header wall
above door.
If headroom clearance is minimal, you
can install the header bracket on the
ceiling. See page 14.
• If you need to install the header
bracket on a 2x4 (on wall or ceiling),
use lag screws (not supplied) to
securely fasten the 2x4 to structural
supports as shown.
• Open your door to the highest point of
travel as shown. Measure the distance
from the top of the door to the floor.
Subtract the actual height of the door.
Add 8" to the remainder. (See
Example).
• Close the door and draw an
intersecting horizontal line on the
header wall at the determined height.
If the total number of inches exceeds
the height available in your garage,
use the maximum height possible, or
refer to page 14 for ceiling
installation.
Proceed to Step 2, page 14.
