Da-Lite 21791LS Tensioned Advantage Electrol Projection Screen, 106D

Optimize your control rooms, training centers and security monitoring suites with the Da-Lite by Legrand Tensioned Advantage Electrol projection screen. This professional-grade, in-ceiling projection screen (model 21791LS) delivers a tensioned, ripple-free viewing surface that preserves image fidelity for presentations, surveillance video walls and critical monitoring applications. The 106-inch diagonal, 16:9 aspect format supports modern projectors and multi-camera surveillance feeds, while electric operation and the included wall switch make scene changes and scheduled use effortless.

Designed for contractors and AV integrators, the Tensioned Advantage Electrol includes pre-installed ceiling trim and sliding installation brackets so the screen case can be positioned during rough-in and finished later—minimizing downtime and on-site trade coordination. The tensioned fabric reduces hotspotting and wrinkles for consistently clear images across the entire surface. TAA compliance and a 5-year limited warranty simplify procurement for government and enterprise security projects.

Install this ceiling-mounted solution in conference rooms, control centers and surveillance hubs to streamline installation and enhance monitoring clarity. Contact your AV supplier or order the Da-Lite Tensioned Advantage Electrol to upgrade your facility’s projection and surveillance setup.
