Dunbarton Door and Entry Systems began its innovative journey over sixty years ago in post-World War II Detroit, Michigan. William A. Ternes established Ternes Steel Company, Dunbarton’s founding company, in 1946 to develop military housing. In 1954 the company took an even wider turn in its manufacturing expertise by designing and producing the first steel bifold closet door. In 1972 the company moved to Dothan, Alabama. By this time, the company also added a new product to its manufacturing processes: the steel door frame, later to be known as Rediframe. Today, Dunbarton manufactures four building product lines: Rediframe Door Frames, Slimfold Closet Systems, AtHome Steel and Fiberglass Doors, and Achiever Entry Systems.
