Overview
Clopay is described on its official site as North America's largest garage door manufacturer and an industry leader in the design and production of residential and commercial garage doors as well as industrial rolling steel doors. Its products are sold through a network of over 3,000 independent professional dealers and retailers, including The Home Depot. The company traces its story to 1859 with the Benard Seinsheimer Corporation, a Cincinnati-based paper wholesaler, and adopted the name 'Clopay' during the 1930s. It entered the garage door business in 1964 with the acquisition of Baker-Aldor-Jones of Hialeah, Florida, and is headquartered in Mason, Ohio, operating four U.S. manufacturing facilities and over 55 distribution centers.
History
Clopay's story begins in 1859 with the Benard Seinsheimer Corporation, a Cincinnati-based paper wholesaler. During the 1930s, the company adapted with the times, manufacturing blackout window shades during the war and adopting the name 'Clopay'—an inventive acronym for 'cloth and paper.' The chapter that defines Clopay today began in 1964, when the company entered the garage door business with the acquisition of Baker-Aldor-Jones of Hialeah, Florida. Within just a few years, Clopay expanded its manufacturing footprint to Russia, Ohio, where the facility quickly became the center of its garage door operations. Headquartered in Mason, Ohio, Clopay now operates four state-of-the-art manufacturing facilities in the United States and supports a vast network with over 55 distribution centers.
