The ELCOR Manual Slow Retraction Mechanism Pull-Down Projection Screen (100-Inch) is engineered for smooth, safe and silent operation in classrooms, meeting rooms, hotel conference rooms and home theatres. The specially built-in Slow Retract Mechanism allows a quiet, controlled return of the screen to its housing — protecting both the screen fabric and anyone standing nearby. Imported Matte White Fabric The screen features imported matte white fabric with a 1.1 gain and a 160-degree wide viewing angle for commercial presentations and residential home cinema. Fully 4K Ultra HD, Active 3D and HDR Ready. The fabric is black-backed to eliminate light penetration for superior colour reproduction. The standard 4-side black masking border absorbs projector overshoot while enhancing visual contrast. The washable fabric rolls quietly back into the white or black casing after every use. Flexible Installation The dual wall/ceiling mount design allows installation in virtually any room configuration. Includes a screen lanyard for easy pull-down in high or hard-to-reach locations. Available in a wide selection of diagonal sizes in 4:3, 16:9 and 16:10 formats to match any projector setup. White texture powder-coated casing with a clean, professional finish. Not compatible with ultra-short throw projectors. 1-Year Manufacturer Warranty by Elcor Screen (ISO 9001:2015 certified). Lifetime tech support via email, web chat and phone.
