The ABT Trapdoor was designed for large-scale applications in which the screen must completely go undetected when not in use. This line of custom engineered retractable trapdoor screen models consist of the ABT-4 (3.25-inch roller tube) accommodating sizes up to 9' x 12' and ABT-6 (6-inch roller tube) for sizes up to 12' x 16'.

The ABT Trapdoor is available with variety of Stewart's front or rear projection materials. Our exclusive Tab-Guy™ tensioning system ensures a smooth and completely flat screen surface. Matte black over-scan borders* provide a perfectly masked image area.

Microperf X2 and Cinemaperf are available when acoustic transparency is required (acoustically transparent black drop also available upon request).
