The Dalite 16 x 16' Professional Electrol Motorized Projection Screen can be used in large venues such as stage presentations and auditoriums. It can be installed for either an exposed or recessed application (without the doors traditionally associated with a recessed screen). The screen comes oiled-for-life and features an automatic thermal cutoff to prevent burnouts. The braking system is designed to stop the screen in either the "up" or "down" position and prevents "drifting" or "coasting". It includes a three-position Decora style wall switch. The Professional Electrol can be controlled with Dalite's Video Projector Interface, Single Motor Low Voltage Controller, or Dalite's line of Integrated Screen Control products for more sophisticated control and networking.
