Stewart's Horizontal ElectriScreen ElectriMask projection screens are perfect examples of Stewart's industry-leading quality. They're engineered to have seamless screens. The exclusive Tab-Guy Tensioning system prevents edge curl and keeps the screen completely smooth and flat, ensuring a perfect projection surface.

With the Stewart quiet motorized roller system, the screen reliably operates with little noise. Receeds into a ceiling-flush trap doorwhen not in use, and the trap door can also be painted to match the ceiling itself. A hidden alignment ring around the case perimiter assists builders in flush installations.

The Horizontal ElectriScreen ElectriMask combines the flexibility Stewart's ElectriMask system, which converts the image area into a variety of aspect ratios, with a trap-door electric screen. this model supports aspect ratios from standard NTSC 4:3 all the way to the 2.35:1 Cinemascope ratio preferred by Hollywood film directors.
