ONE-PIECE DOOR WITHOUT TRACK
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 celling. See page 14.
If you need to install the header bracket on a 2x4
{on wail or ceiling), use lag screws (not provided)
to securely fasten the 2x4 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 8" 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 inches exceeds the
height available in your garage, use the maximum
height possible, or refer to page 14 for ceiling
installation.
