Griffon Corporation operates through two primary business segments: Home and Building Products (HBP) and Consumer and Professional Products (CPP). The HBP segment, which generates the majority of the company's revenue, operates through Clopay Corporation to manufacture residential and commercial sectional garage doors, rolling steel doors, and grille products. The CPP segment provides branded consumer and professional tools, residential and commercial fans, and home storage products under brands such as AMES, True Temper, Hunter Fan, and ClosetMaid. Historically, Griffon operated in the defense electronics and specialty plastics sectors, but it has strategically divested those businesses to focus on its core building and consumer product lines. The company distributes its products through an extensive network of professional dealers and major home center retail chains.
