RV Day/Night Shades are fabric pleated shades. One half of the shade is made from opaque fabric for privacy and room darkening, and the other half is made from semi-transparent light filtering fabric. They can be found in many types of RVs, mobile homes, campers and conversion vans. These shades are tension mounted, and do not use external cords to operate. You simply push up and pull down on the rails to move the shade.
