Installation
8 Install the Door Bracket
Fiberglass, aluminum or lightweight steel doors WILL REQUIRE reinforcement BEFORE installation of door
bracket. Contact the door manufacturer or installing dealer for operator reinforcement instructions or
reinforcement kit. Failure to reinforce the top section as required according to the door manufacturer may void
the door warranty.
A horizontal and vertical reinforcement is needed for lightweight
doors (fiberglass, 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.
Contact the door manufacturer or installing dealer for operator
reinforcement instructions or 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.

1. Center the door bracket on the vertical center line that was previously marked for the header bracket
installation. Note the correct top placement, as stamped inside the flat bracket.
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.
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:
l
Drill 3/16" fastening holes. Secure the door bracket using the two self threading screws. (Figure1)
l
Alternately, use two 5/16"-18x2" bolts, lock washers and nuts (not provided). (Figure2)
Metal, insulated or light weight factory reinforced doors:
l
Drill 3/16" fastening holes. Secure the door bracket using the self-threading screws. (Figure3)
