• 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 10.
• 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.
EXAMPLE
Distance from top of door
(at highest point of travel) to floor................................92"
Actual height of door...................................................-88"
Remainder.......................................................................4"
Add...............................................................................+8"
Bracket height on header wall....................................=12"
(Measure UP from top of CLOSED door.)
Proceed to Step 2, page 10.

ONE-PIECE Door Without Track
• 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 10 for ceiling installation.
