Da-Lite 21799L 159" Ceiling Recessed Electric Screen with Plenum Rated Aluminum Case and Trim Flange, or Automatic Closure Door

Optimize large-scale AV and monitoring environments with the Da-Lite by Legrand Tensioned Advantage Electrol projection screen — a ceiling-recessed electric screen built for professional installations. Engineered for control rooms, security command centers and corporate auditoriums, this 159" diagonal (16:9) screen provides a tensioned, museum-flat viewing surface that minimizes image distortion and improves projector image uniformity. The UL plenum-rated aluminum case and white powder-coated finish deliver code-compliant installation in plenum spaces while the integrated trim flange conceals rough openings to cut finishing labor.

Electric operation paired with Low Voltage Control (LVC) and a Decora-style 3-button wall switch gives installers flexible, reliable control for AV automation and building management systems. The screen’s black backing and standard 12" black drop preserve contrast and projected brightness, making it ideal for security, surveillance and monitoring applications where clarity and repeatability matter. Choose this Da-Lite projection screen for professional AV, surveillance operations, or executive presentation spaces — contact your integrator to specify mounting, control options and fabric type for your next installation.
