CineTension 2 WraithVeil Dual is a sturdy, well-made electric motorized projector screen that has front and rear-projection capabilities. Its tab-tensioned material provides uniform flatness for exceptional projected image clarity. The Wraith Veil Dual material presents a bright, clear image on both sides when projected upon from either angle. This versatile fabric gives optimal results under controlled room lighting while maintaining excellent performance under mild levels of ambient lighting with a high lumens (output) projector. The screen drops and retracts by means of a powerful tubular motor. Its sliding installation brackets ensure a perfectly centered installation.
