Da-Lite Horizon Electrol Projection Screen

The Horizon Electrol is the first screen available allowing four-position masking with the touch of a button. Dry contacts are provided on the electronic controller so you can adjust the screen to the factory presets from a properly equipped projector or master control. Careful engineering ensures the masking remains flush against the surface of the screen, preventing distracting shadows around the image. Patented in-the-roller motor mounting system allows for quiet operation. Equipped with a six-button wall switch, you can automatically open and close the screen, halt operation and position the screen into any of the four aspect ratios.
