The ABT Trapdoor projector screen by Stewart was designed expressly for situations in which the screen must be completely hidden when it's not being used.

The ABT Trapdoor can be custom made with any of Stewart's award-wining screen materials. The exclusive Stewart Tab-Guy tensioning system promises a smooth, flat and perfect surface for an ideal image. The matte black border (including 12" of black drop, unless otherwise specified) results in a perfectly masked image area, while absorbing excess projection light.

*It is important to add only the amount of black drop needed. Side and bottom masking determined by the amount of black drop and image size.

		Stweart makes some of the finest screens in the world, and has established a reputation for world-class quality. In fact, the control room at CNN was designed using Stewart screens, so you've probably seen a Stewart screen already1!
