Griffon Corporation
A diversified American holding company built around two businesses: garage doors and rolling steel doors under the Clopay brand (North America's largest maker, sold through dealers plus Home Depot and Menards), and household goods under brands like AMES tools, Hunter fans, and ClosetMaid storage. It traces its roots to a Cincinnati paper wholesaler from 1859, whose "Clopay" name is an acronym for "cloth and paper," and it adopted the Griffon name in 1995.
