Da-Lite 21771 Tensioned Advantage Deluxe Electrol Projection Screen, 137D

Deliver crisp, undistorted images for critical AV, security and surveillance environments with the Da-Lite by Legrand Tensioned Advantage Deluxe Electrol projection screen. Designed for control rooms, monitoring centers and executive presentation spaces, this electric, tensioned projection screen produces a smooth viewing surface for precise image reproduction. The 137" diagonal viewing area (116" wide x 72.5" high) gives you a large, consistent canvas ideal for multi-camera surveillance feeds or data dashboards.

Installation fits construction workflows — the UL Plenum-rated case mounts in the ceiling during rough-in and the fabric assembly is installed at finish, while the integrated trim and closure door maintain a clean ceiling line. Smooth Roll Technology and a black-backed material retain brightness and eliminate seams, improving readability of security and monitoring content. Motorized operation with Low Voltage Control plus a Decora-style wall switch provides simple, repeatable control for scheduled or on-demand use. Backed by GREENGUARD certification and a 5-year limited warranty, the 21771 is engineered for long-term reliability.
