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

Installation procedures vary according to garage door types. Follow the instructions which apply to your door.

1.1Close the door and mark the inside vertical centerline of the garage door.

1.2Extend 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.

1.3Open 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.

•2" (5 cm) above the high point for sectional door and one-piece door with track.

•8" (20 cm) above the high point for one-piece door without track. 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.
