•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.
