Da-Lite 21798LS projection screen 133" 16:9

Tensioned Advantage Electrol
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.
Tensioned screens ensure the smoothest surface possible.
The Tensioned Advantage® Electrol® screen features simple in ceiling installation that can be done in two 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 Tensioned Advantage Electrol does not include the automatic closure door. See Tensioned Advantage Deluxe Electrol for the additional aesthetic of the automatic closure door.
