Camco's Standard RV Roof Vent Cover is designed to allow fresh air ventilation and light into your RV—rain or shine. It installs over your existing 14-inch x 14-inch RV roof vent, allowing you to open your vent without impeding air flow. Removable louvers allow easy roof vent access for simple maintenance and cleaning. The cover’s aerodynamic design offers high-flow ventilation and includes a built-in insect screen. Made of durable resin, the vent cover measures 19 5/16-inches (front to back) x 18 ½-inches (wide) x 9 3/8-inches (tall) OD. Mounting hardware is included.
