In 1947, Tru-Roll was created as a division of Grosh to manufacture theatrical equipment in support of a growing entertainment industry in Southern California. Within a few short years, Tru-Roll’s success enabled it to expand into the fast growing theme park and Las Vegas entertainment industry, eventually becoming a major national manufacturer of stage equipment. In late 2009, Advanced Entertainment Technology was presented with the unique opportunity to purchase Tru-Roll. As a division of AET, Tru-Roll continues to provide its signature drapery tracks and quality theatrical equipment worldwide.
