In 1968, John Bellart, president and owner, made a bid to purchase a small window manufacturer in Green Bay, Wisconsin. Already owning a successful electrical contracting business, and several bowling centers in the Milwaukee area, John and his partner saw a "window" of an opportunity. They purchased the company, moved it to Milwaukee, and founded Unlimited, Inc. Unlimited, Inc. began by producing only one window line: a steel basement window for use in poured concrete walls. The business was prosperous for the two entrepreneurs, even as it was only a side interest. The company remained only with one product until 1980.
