Install the door bracket
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.
SECTIONAL DOORS
8.1
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.
8.2
Position the top edge of the bracket 2"-4" (5-10 cm) below the top edge of the door, OR directly below
any structural support across the top of the door.
8.3
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.
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.
