Fiberglass, aluminum or lightweight steel garage doors
WILL REQUIRE reinforcement BEFORE installation of door
bracket. Contact your door manufacturer for reinforcement kit.
INSTALLATION STEP 12
Fasten the Door Bracket
Follow instructions which apply to your door type as illustrated
below or on the following page.
A horizontal reinforcement brace should be long enough to be
secured to two vertical supports. A vertical reinforcement 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, two pieces of angle iron are used
to create a U-shaped support (Figure 1). The best solution is
to check with your garage door manufacturer for an opener
installation door reinforcement kit.
Note: Many vertical brace installations provide for direct
attachment of the clevis pin and door arm. In this case you will not
need the door bracket; proceed to Installation Step 13.
SECTIONAL DOORS
1. Center the door bracket on the previously marked vertical
centerline used for the header bracket installation. Note correct
UP placement, as stamped inside the bracket (Figure 2).
2. 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
edge of the door.
• The top edge of the bracket directly below any structural
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.
