Fiberglass, aluminum or lightweight steel garage doors WILL 
REQUIRE reinforcement BEFORE installation of door bracket. 
Contact your door manufacturer for reinforcement kit.
INSTALLATION STEP 11
Fasten the Door Bracket
A horizontal brace should be long enough to be secured to 2 
vertical supports. A vertical brace should cover the height of the 
top panel. 
The illustration shows one piece of angle iron as the horizontal 
brace. For the vertical brace, 2 pieces of angle iron are used to 
create a "U"-shaped support. The best solution is to check with 
your garage door manufacturer for an opener installation door 
reinforcement kit.
Center the door bracket on the previously marked vertical • 
guideline used for the header bracket installation.
Position the bracket on the face of the door within the following • 
limits: 
The top edge of the bracket 2"-4" (5-10 cm) below the top A) 
edge of the door.
The top edge of the bracket directly below any structural B) 
support across the top of the door.
Mark and drill 5/16" left and right fastening holes. Secure the • 
bracket as shown in Figure 1 if there is vertical reinforcement.
If your installation doesn't require vertical reinforce ment but does 
need top and bottom fastening holes for the door bracket, fasten 
as shown in Figure 2.
