This 69\" x 110\" (130\" diagonal) unit features the HD Progressive 1.0 surface, which is engineered for high-resolution front projection. Built for large venue environments, this screen utilizes a 120V (60Hz) motor and is TAA compliant. The design includes an automatic closure door and a standard black drop to manage the appearance of the projection area. Because this is the Case\/Box Only for Rough-In product selection, the screen housing is intended to be installed during the rough-in construction stage, allowing the screen surface assembly to be completed during the finishing stage. The white powder-coated case offers a clean aesthetic for recessed installation, and the UL plenum rated case ensures compliance with fire safety requirements in ceiling environments. For smooth, flat projection, the TruGuide™ Electric Screen Tensioning System is integrated into the single roller design.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e69\" x 110\" (130\" diagonal) projection area with HD Progressive 1.0 surface\u003c\/li\u003e\n\u003cli\u003eCeiling recessed application with UL plenum rated white powder-coated case\u003c\/li\u003e\n\u003cli\u003eTruGuide™ Electric Screen Tensioning System for a smooth, flat viewing surface\u003c\/li\u003e\n\u003cli\u003eStandard 120V (60Hz) motor with standard low voltage control\u003c\/li\u003e\n\u003cli\u003eAutomatic closure door and standard black drop for high-resolution front projection\u003c\/li\u003e\n\u003cli\u003eTAA compliant for government and regulated installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuestions\u003c\/h2\u003e\u003ch3\u003eIs the Da-Lite 21770B TAA compliant?\u003c\/h3\u003e\u003cp\u003eYes, this model is TAA compliant and is manufactured in the US.\u003c\/p\u003e\u003ch3\u003eWhat is the installation process for this recessed screen?\u003c\/h3\u003e\u003cp\u003eThis is a Case\/Box Only for Rough-In selection, meaning the housing is installed during the rough-in stage, while the surface assembly is installed during the finishing stage.\u003c\/p\u003e\u003ch3\u003eWhat type of control is used with the 21770B?\u003c\/h3\u003e\u003cp\u003eThe screen features standard low voltage control (LVC) and is compatible with accessories like the Da-Lite 40975 Low Voltage Wall Switch.\u003c\/p\u003e\u003ch3\u003eDoes this screen require a black drop?\u003c\/h3\u003e\u003cp\u003eYes, this specific SKU includes a standard black drop to maintain the appearance of the projection area.\u003c\/p\u003e\u003ch3\u003eCan I add a locking cover to the wall switch?\u003c\/h3\u003e\u003cp\u003eYes, the Da-Lite 98837 Locking Switch Cover Plate is compatible with this series.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eSpecifications are supplied by the manufacturer.
