The 20325EF 45 x 80" Tensioned Advantage Deluxe Electrol Fabric, Roller, and 220 VAC Motor by Da-Lite is meant to be used along with its separately sold Tensioned Advantage Deluxe in-ceiling screen box. The in-ceiling box to house these parts (complete with wiring for this motor) must be purchased separately. The screen motor is designed to operate in a 220 VAC electrical system only.

The HD Progressive 1.1 Perf surface has a 1.1 gain, 170° viewing angle, and is ideal for applications where projector brightness and screen size require an increase in gain. The white surface offers true color reproduction and fidelity. This vinyl viewing surface is perforated, allowing you the option of placing your speakers behind the screen. HD Progressive 1.1 Perf can be cleaned with mild soap and water, and is flame retardant and mildew resistant. It is also GREENGUARD GOLD Certified.

Sound waves will pass through the screen and out towards the audience in front. This gives you more options for speaker placement in your room, and is also useful in instances where space is limited.

Correct Screen Box and Wiring are Required - See Description
