The EcoCell cellular design expands and contracts effortlessly, allowing you to adjust the shade with ease while maintaining a clean, modern look. Snap on shade measures 11-7/8" X 21-1/2". Note: This Thin Shade EcoCell RV window shade is made for prepped Lippert RV entry doors only (look for the "Thin Shade Ready" decal on your window).
