The white 120V 140040U Access/Series V 87.5 x 140" Ceiling-Recessed Screen with LVC-IV Low Voltage Controller from Draper is a tab-tensioned screen for ceiling-recessed installation. It is designed to enable you to install the case during the "dirty" phase of the construction process and keep the screen safe until you install the projector. The screen (motor-in-roller and attached viewing surface) installs quickly with preset latching roller brackets and electrical pin connectors. This eliminates job site damage.
