1.Close the door and mark the inside vertical centerline of your garage door. Extend the line onto the header wall above door, as shown.
If headroom clearance is minimal, you can install the header bracket on the ceiling. See page 18.
If you need to install the header bracket on a
38 mm board (on wall or ceiling), use lag screws (not provided) to securely fasten the 38 mm board to structural supports as shown.
2.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 20 cm to the remainder. (See Example).
3.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 18 for ceiling installation.
