Carls Gray Rear Projection Film (16:9 | 86x153 | 175-in | Folded) Grey Rear Projection Material, Rear Projection Screen Material, Rear Projection Projector Screen, Translucent Projection Fabric Gray Rear Projection Screen Material is a great way to hide your projection equipment behind the screen when you have a low light environment (such as stage lights) because its translucent gray (Not transparent, Not clear) surface adds extra contrast and deeper blacks when your projector is completing with light in the room. Gray Rear Projection Film Screens are a high-tech product which feature a natural and clear, HD image. Gray Rear Projection Film Material is best for a wooden fixed frame where it will be tension-mounted/pulled tightly and evenly in all four directions (like an artist canvas). The translucent gray rear projection film surface works best with a bright projector (2,000+ lumens) and offers a narrow viewing angle/audience seating area. Mount the projector off-axis; high, low or off to the side. Any object or person between the projector and the screen will show through the material. Note: Our Grey Rear Projection Screens do NOT have an adhesive backing and is NOT a static cling. Not recommended for use with a short throw projector due to risk of hot spots. You can also use this product for front projection although you may loose some brightness. You should project onto the smooth side of Carl's Rear Projection Screens. * Ships folded in a box by default, but select sizes have an option to ship rolled on a tube as well.
