The Yard Master Electric Tension Series is an electric screen with 2-way projection material that is IP33 rated for wind/rain penetration for outdoor applications. The tab-tension design supports a front/rear projection surface with perfect uniform flatness. This allows you to use either a standard short throw or UST projectors. The WraithVeil® Dual material provides superb image clarity from in-front or behind and its diverse projector compatibility makes it a must for outdoor home or commercial video applications. It is ideal for nighttime movie presentations. The screen comes with a Radio Frequency remote control that doubles as a wireless 12-volt projector trigger that coordinates the screen's drop and rise with the projector's power cycle.
