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 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 bracketon a 2x4 (on wall or ceiling), use lag screws (not
provided) to securely fasten the 2x4 to structural supports.
3. Open your door to the highestpoint of travel as shown.Draw an intersecting horizontal line on
the header wall 2" (5 cm) above the high point :
l
2" (5 cm) above the high point for sectional door and one-piece door with track.
l
8" (20 cm) above the high pointfor one-piece door withouttrack.
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 12 for
ceiling installation.

STEP 8 Install the door bracket
Fiberglass, aluminumor lightweightsteel garage doors WILLREQUIRE reinforcementBEFORE
installation of door bracket. Contact your door manufacturer for reinforcement kit.
Figure 1 shows one piece of angle iron as the horizontal brace. For the vertical brace, 2 piecesofangle
iron are used to create a U-shaped support. The bestsolution is to check with your garage door
manufacturer for an opener installation door reinforcement kit.
NOTE: Many door reinforcement kits provide for directattachment of the clevis pin and door arm. In this
case you will not need the door bracket; proceed to the next step.
A horizontal and vertical reinforcementis needed for
li
ghtweight garage doors (fi
berglass, aluminum, steel,
doors with glass panel, etc.) (not provided).
A horizontal reinforcement brace should be long
enough to be secured to two or three vertical supports.
A vertical reinforcement brace should cover the height
of the top panel.
