The Da-Lite 21824BL is a large venue Tensioned Advantage Series electric screen designed for ceiling recessed applications. This 135" x 240" (275" diagonal) unit is engineered for front projection, utilizing a high-resolution HD Progressive 1.0 surface to ensure clear image delivery. The series is built for professional installation via a two-stage process: the screen case can be installed during the rough-in construction stage, while the screen surface assembly is completed during the finishing stage. This specific SKU features a standard 120V (60Hz) motor and comes with standard black drop and a slot-style closure door. The white powder-coated case is designed to sit flush with the ceiling, concealing the rough opening with integrated ceiling trim to eliminate the need for additional trim work. This TAA compliant screen utilizes the TruGuide™ Electric Screen Tensioning System and Smooth Roll Technology to maintain a perfectly flat viewing surface. For control, it includes standard low voltage control, and is compatible with accessories like the Da-Lite 40975 Low Voltage Wall Switch.
