STEP 8 Install the door bracket
Fiberglass,aluminum or lightweightsteel garage doors WILLREQUIRE reinforcement BEFORE
installation of door bracket.Contactyour door manufacturer for reinforcement kit.
Figure 1 showsone 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 checkwith 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.
A horizontal and vertical reinforcementis needed for
li
ghtweight 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.
