00-933081 MaxxAir II is a translucent white roof vent cover designed to protect recreational vehicle interiors from rain while allowing fresh air to circulate. Its aerodynamic design and side louvers provide increased ventilation, helping release heat, stale air and cooking odors. Made of polyethylene, it fits most standard 14" x 14" roof vents. Hinged mounting hardware allows convenient opening for cleaning and roof vent seal inspection. A limited six-year manufacturer warranty applies.
