The ELCOR Manual Auto-Lock Projection Screen (150-Inch) is a large-format ELCOR Lite Series manual pull-down screen built for auditoriums, large classrooms, lecture halls, hotel ballrooms and premium home cinema installations. With a viewing area of 74\" H × 131\" W, this screen delivers a truly cinematic experience in any large-scale venue. Fibre-Glass Backed Multi-Layer Fabric The screen features a premium matte white fabric with 1.1 gain — fibre-glass backed with a multi-layer weave construction for exceptional flatness, durability and long-term performance. The fully black-backed surface eliminates light penetration entirely, and the textured surface ensures even light diffusion across the full 150-inch viewing area. A wide 180-degree viewing angle ensures a bright, clear image from any seat in a large room. The material is 4K Ultra HD, Active 3D and HDR Ready. Auto-Lock Design & Installation The built-in Auto-Lock / Insta-Lock mechanism holds the screen at any desired height without hooks — especially useful in large rooms where partial screen deployment is needed. The screen is housed in a slim, moisture-resistant white aluminium casing with a 12-inch drop-down black border on top to absorb extra light. Screen lanyard, wood screws and drywall anchors are included. Not compatible with ultra-short throw projectors. SKU: EL150INILS. 1-Year Manufacturer Warranty by Elcor Screen, ISO 9001:2015 certified.
