INSTALLATION STEP 1

Determine the Header Bracket

Location

To prevent possible SERIOUSINJURYor DEATH:

•Header bracket MUST be RIGIDLYfastened to structural support on headerwall or ceiling, otherwise garagedoor might not reversewhen required. DO NOTinstall header bracket over drywall.

•Concreteanchors MUST be used if mounting header bracket or 2x4 into masonry.

•NEVERtry to loosen, move or adjust garagedoor, springs, cables, pulleys, brackets, or their hardware, all of which are under EXTREMEtension.

•ALWAYScall a trained door systems technician if garage door binds, sticks, or is out of balance. An unbalanced garagedoor might not reversewhen required.

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

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

2.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

(see page 13) 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 as shown here and on page 13.

3.Open your door to the highest point of travel as shown. Draw an intersecting horizontal line on the header wall above the high point:

•3" (7.5 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.
