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.

lightweight garage doors (fiberglass, aluminum,steel,doors
