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.
