This Tensioned Advantage series model features a 146\" x 260\" screen size, providing a 298 in (756.9 cm) diagonal for expansive viewing. It is engineered with an HD Progressive 1.0 high-resolution surface and a standard black drop, which helps retain projected brightness on front projection surfaces. For professional installations, this unit includes an automatic closure door and standard low voltage control (LVC) for integrated operation. The white powder-coated case is UL Plenum rated for safe installation in many ceiling environments. Because this is a 'Case\/Box Only for Rough-In' selection, it is designed to be installed in two stages: the screen case is mounted during the rough-in construction phase, while the screen surface assembly is installed during the final finishing stage. This process allows the ceiling trim to be in place before the surface is deployed, concealing the rough opening and eliminating the need for additional trim work.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLarge venue 146\" x 260\" (298\" diagonal) projection surface\u003c\/li\u003e\n\u003cli\u003eHD Progressive 1.0 high-resolution surface for front projection\u003c\/li\u003e\n\u003cli\u003eTwo-stage installation with case installed during rough-in\u003c\/li\u003e\n\u003cli\u003eAutomatic closure door and standard low voltage control\u003c\/li\u003e\n\u003cli\u003eTruGuide™ Electric Screen Tensioning System for surface smoothness\u003c\/li\u003e\n\u003cli\u003eSmooth Roll Technology maintains a perfectly flat screen\u003c\/li\u003e\n\u003cli\u003eUL Plenum rated white powder-coated case\u003c\/li\u003e\n\u003cli\u003eTAA Compliant for government and specialized contracts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuestions\u003c\/h2\u003e\u003ch3\u003eHow does the installation process work for the 21784EB?\u003c\/h3\u003e\u003cp\u003eThis model follows a two-stage installation.
