Da-Lite Tensioned Advantage Series, 146" x 260" with HD Progressive 1.0 - 21784EB
Large venue ceiling recessed electric screen, 146" x 260" dimensions with HD Progressive 1.0 surface and automatic closure door
The Da-Lite 21784EB is a large venue, ceiling recessed electric screen designed for high-impact projection environments. 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.
