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.

but does need top and bottom fastening holes for the
door bracket, fasten as shown in Figure 2.
