Dalite's Deluxe Model B projector screen is a cut above the rest of the manual projector screens on the market. Much like the normal Model B, it's perfectly suited for training and meeting rooms, classrooms, offices and board rooms, what sets it apart, however, is it's built in tensioning.
The Deluxe Model B comes with a built-in tensioning arm, that locks into place when the screen is extended. This provides a flat, tensioned viewing surface for improved picture quality.
The screen surface may also be angled with a pull cord to eliminate keystoning when mounted with extension brackets or suspended from the ceiling.
