The Da-Lite 38786LS 45 x 80" Tensioned Contour Electrol Wall/Ceiling Screen Lite has a black extruded aluminum case with a veneer curved front and a silent motor that makes 30% less noise than Da-Lite's standard motor. Also included is an on-board Low Voltage Control for use with IR or RF remotes (sold separately), and a three-position Decora-style wall plate. The HD Progressive 0.9 surface has a 0.9 gain, 170° viewing angle, and is used with moderate to high output projectors. The light gray surface achieves an ideal balance between color reproduction and image contrast. The seamless surface can be cleaned with mild soap and water and is flame-retardant and mildew-resistant. It is also GREENGUARD GOLD Certified.
