minimal, you can install the
header bracket on the ceiling.

• 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.
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.
Proceed to Step 2, page 12.
