This Large Advantage Deluxe Electrol 4:3 Video Format Motorized Projection Screen from Da-Lite has a 177.0 x 236.0" viewing area with a High Power flame retardant and mildew-resistant finish.
High Power has a 2.4 Gain rating and 30° viewing angle. It is similar to a traditional glass beaded finish but has the ability to be cleaned. The textured surface has a very high gain rating and is recognized for its ability to throw light back against the projection axis. Therefore, it works best when placed in the same horizontal viewing plane as the audience. It is suitable for venues where ambient light is an issue. This finish comes with black backing for opacity and standard black masking borders.
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. It should be noted that this version of the screen has a wider casing to accommodate a larger roller.
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.
