Moen was originally part of Ravenna Metal Products of Seattle, Washington. In 1956 it became part of Stanadyne, Inc., and was that company's only consumer brand. Stanadyne was acquired in 1988 by Forstmann-Little & Company. In 1989, Moen was given the status of an independent company and renamed Moen Incorporated. A year later, in 1990, Moen was purchased by MasterBrand Industries, Inc., an operating company of American Brands. American Brands became Fortune Brands in 1997, and Moen is now part of the Fortune Brands Home and Hardware group.
