Installation
1 Determine the Header Bracket Location
To prevent possible SERIOUS INJURY or DEATH:
• Header bracket MUST be RIGIDLY fastened to structural support on header wall or ceiling,
otherwise garage door might NOT reverse when required. DO NOT install header bracket
over drywall.
• Concrete anchors MUST be used if mounting header bracket or 2x4 into masonry.
• NEVER try to loosen, move or adjust garage door, springs, cables, pulleys, brackets, or
their hardware, ALL of which are under EXTREME tension.
• ALWAYS call a trained door systems technician if garage door binds, sticks, or is out of
balance. An unbalanced garage door might NOT reverse when required.
• DO NOT enable the Timer-to-Close functionality if operating either one-piece or swinging
garage doors. To be enabled ONLY when operating a sectional door.
Close the door and mark the inside vertical centerline of the garage door.
Extend the line onto the header wall above the door. You can fasten the header bracket within 4 feet
(1.22 m) of the left or right of the door center only if a torsion spring or center bearing plate is in the
way; or you can attach it to the ceiling when clearance is minimal. (It may be mounted on the wall
upside down if necessary, to gain approximately 1/2" (1 cm). If you need to install the header bracket
on a 2x4 (on wall or ceiling), use lag screws (not provided) to securely fasten the 2x4 to structural
supports.
Open your door to the highest point of travel as shown. Draw an intersecting horizontal line on the
header wall 2" (5 cm) above the high point. This height will provide travel clearance for the top edge
of the door.
NOTE: If the total number of inches exceeds the height available in your garage, use the maximum
height possible, or refer to page 13 for ceiling installation.
