Designed to eliminate the extra step of finishing the screen with trim, the Advantage line of projection screens is designed with ceiling trim already in place. Once the screen is installed, the screen's trim conceals the rough opening eliminating the need to complete additional trim work. Sliding installation brackets make it easy to attach the screen housing to the structure above the drop ceiling. The Advantage Electrol screen features simple in-ceiling installation that can be done in 2 stages. The screen case can be installed during the rough-in construction stage and the fabric assembly can be completed during the finishing stage. The Advantage Electrol does not include the automatic closure door or the Tensioning Cable System. See Tensioned Advantage Electrol for Tensioning Cable System or Tensioned Advantage Deluxe Electrol for both the Tensioning Cable System and the additional aesthetic of the automatic closure door.
