Fiberglass,aluminum or lightweightsteel garage doorsWILLREQUIRE reinforcement BEFORE
installation of door bracket. Contact the garage door manufacturer or installing dealer for opener
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 garage doors (fiberglass, aluminum,steel,
doors with glasspanel, 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 ofthe top panel. Contact the
garage door manufacturer or installing dealer for opener

case you will not need the door bracket; proceed to the next step.
