Housed in an attractive black pentagonal steel case, the crank-operated Premier C wall-or ceiling-mounted, tab-tensioned projection screen comes with a crank handle for enhanced screen security. The detachable crank handle provides an added benefit of limiting screen access within educational or business-related environments. Tab-tensioned screens provide a perfectly flat viewing surface with better image quality. RF welded tabs create a more durable seal that eliminates separation and stickiness.
