Profile: D R H (Screens) Ltd. specializes in projection screens. Our products include manual wallscreen, electric wallscreen, tripod screen, portable floor screen, heavy duty Imperial electric screen, and fast Ford portable screens. Heavy-duty rigid plastic casing will handle the knocks and retain appearances. Our heavy duty Imperial electric screen is designed with heavy usage in mind. The Imperial's rolling mechanism employs bigger 63 mm dia tubing, and the workhorse 240V motor. The larger components used are reflected in the overall dimensions of the casing. We offer screens with aluminum backed velvet covered frames and mobile projection screens.
