This Tensioned Advantage Deluxe Electrol 16:10 Wide Format Motorized Projection Screen from Da-Lite has a 65 x 104" viewing area with a DA-Tex flame retardant and mildew-resistant finish.

DA-Tex is a rear screen, translucent neutral gray finish with a 1.3 Gain rating and 30° (L/R) viewing angle. It is characterized by high transmission and low reflectance values. Color rendition is true and contrast is good. This finish is especially suitable for lace and grommet screens. If the finish becomes soiled, it can be cleaned with mild soap and water. Tensioning on each side of the seamless fabric assures a flat, undistorted surface that eliminates any chance of a skewed image.

One of the major advantages of this screen is that the fabric roller can either be factory installed or at your chosen location after the ceiling recessed, UL Plenum rated extruded aluminum white housing has been roughed in. The enables you to finish the initial installation but choose your screen finish at a later date.

The screen includes two motors; one for the ceiling door and one for the fabric. The interior roller features a quick reversal motor, oiled for life, with automatic thermal overload cutout, integral gears, capacitor, and an electric brake to prevent coasting when the screen is stopped at a chosen length. The built-in Low Voltage Control controls up/down and stop functions using the included 12VDC three-position switch that can be wall mounted where convenient. It can also be operated from an optional radio frequency, infrared or auxiliary transmitter.
