Like all Stewart Filmscreen products, the ABT Vertical ElectriScreen ElectriMasks are engineered with totally seamless screen materials (this includes masking borders). To prevent edge-curl and insure a flat image, Stewart utilizes our exclusive Tab-Guy™ tensioning system. Stewart’s motorized roller system provides a quiet, reliable screen operation. The screen retracts into an obscure trapdoor that mounts flush, and can be painted to blend perfectly, with the ceiling surface, efficiently hiding its existence. Stewart Filmscreen’s trapdoor systems each feature a motorized, aluminum trapdoor which closes when screen is not in use. For flush-mount installations, the systems also each feature a builder-friendly, hidden alignment ring around the box perimeter. Stewart Filmscreen’s ABT Vertical ES EM is designed to provide the flexibility of a multiple aspect ratio ElectriMask system with a roll-up screen. Aspect ratios from standard NTSC 1.33:1 up to Widescreen 1.85:1 can be achieved.
