• 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 12.
• If you need to install the header
bracket on a 25mm board (on
wall or ceiling), use lag screws
(not supplied) to securely
fasten the 25mm board to
structural supports as shown.
EXAMPLE
Distance from top of door
(at highest point of travel) to floor .....................234cm
Actual height of door......................................– 224cm
Remainder ..........................................................10cm
Add ..................................................................+ 20cm
Bracket height on header wall .........................= 30cm
(Measure UP from top of CLOSED door.)
Proceed to Step 2, page 12.

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 20cm to the remainder. (See Example).
• Close the door and draw an intersecting horizontal
line on the header wall at the determined height.
NOTE: If the total number of centimeters
exceeds the height available in your garage, use
the maximum height possible, or refer to page
12 for ceiling installation.
