Elite ProAV presents the Manual Tab-Tension Series, as its premium grade non-electric large venue projector screen. The design features a manually operated bead chain clutch mechanism with a swift rolling sprocket that allows the material to stop at any point of its drop/rise operation. The tab-tension system allows the projection surface to be flat and taut so that ultra/short throw projectors may be used with this screen as well. The housing is of a sturdy white enameled aluminum construction. It is moisture resistant and available in a white finish. It includes flush sliding wall brackets that align with wall studs while allowing the installation to be perfectly centered.
