Da-Lite 21871L 220" Tensioned Cosmopolitan Series Wall or Ceiling Mounted Electric Screen

Built for large venues and mission-critical monitoring, the Da-Lite by Legrand 21871L Tensioned Cosmopolitan electric projection screen creates a reliably flat, high-contrast 220" viewing surface ideal for professional AV, security and surveillance environments. This wall- or ceiling-mountable projection screen integrates Da-Lite's TruGuide tensioning and Smooth Roll Technology to eliminate ripples and maintain image uniformity across the full 16:9 aspect display, so video feeds and presentations remain sharp and readable.

Designed for integrators and facilities managers, the Cosmopolitan series offers flexible control options — including low-voltage control, a projector trigger and a silent motor — to support automated systems and minimize disruption in control rooms. The durable two-piece aluminum case (standard white, black on request), GREENGUARD Gold certification and TAA compliance make it suitable for public-sector installations. With a standard black backing to retain brightness and seamless front projection surfaces, the 21871L is optimized for conference rooms, training centers, and security operations centers.
