Fiberglass, aluminum or lightweight steel garage doors
WILL REQUIRE
reinforcement BEFORE
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 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.
NOTE:
Many door reinforcement kits provide for direct attachment
of the clevis pin and door arm. In this case you will not need the
door bracket; proceed to the next step.

Mark, drill holes and install as follows, depending on your door’s construction:
Metal or light weight doors using a vertical angle iron brace between the door panel support
and the door bracket:
• Drill 3/16" fastening holes. Secure the door bracket using the two self threading screws.
(Figure 2)
• Alternately, use two 5/16" bolts, lock washers and nuts (not provided). (Figure 3)
Metal, insulated or light weight factory reinforced doors:
• Drill 3/16" fastening holes. Secure the door bracket using the self-threading screws. (Figure 4)
Wood Doors:
• Use top and bottom or side to side door bracket holes. Drill 5/16” holes through the door and
secure bracket with 5/16"-18x2" carriage bolts, lock washers and nuts (not provided). (Figure 5)
NOTE:
The 1/4"-14x5/8" self-threading screws are not intended for use on wood doors.

Install the door bracket
A horizontal and vertical reinforcement
is needed for lightweight 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.
