Da-Lite 21799L
Tensioned Advantage Electrol 159" Recessed Electric Ceiling Mounted Projector Screen with HD Progressive 0.9 Surface

OUR PART #  21799L


Da-Lite's Tensioned Advantage® Electrol® ceiling mounted projector screen (part no. 21799L) measures 78" x 139" (159" diagonal) and features an HD Progressive 0.9 surface.

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.

Da-Lite's Tensioned Advantage Electrol screens feature 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.

HD Progressive 0.9 Surface

Well-suited for moderate to high output projectors, this light gray surface achieves a perfect balance between color reproduction and image contrast. Seamless in any width up to 16 ft in height.

HD Progressive 0.9 can be cleaned with mild soap and water, is flame retardant and mildew resistant.
