Camco 40433 White RV Roof Vent Cover -- Keep Your Vent Open in Rain and Wind
The Camco 40433 lets you run your roof vent even in rain or gusty conditions without water intrusion. The aerodynamic dome profile deflects wind and rain while the built-in insect screen keeps bugs out. Made from UV-stabilized resin that holds its color season after season -- no chalking, no yellowing. Fits the standard 14" x 14" vent opening found on the vast majority of RV and travel trailer roofs.
Running a roof vent in light rain without a cover usually means a wet ceiling, soggy cushions, or a closed vent and a stuffy coach. The Camco 40433 solves that trade-off. Its raised aerodynamic dome channels airflow around the vent opening while blocking rain drops, wind-driven debris, and insects -- so you can leave the vent cracked on a warm rainy night and wake up to a dry interior.
The white finish blends with most OEM vent lids and roof surfaces. The removable louvers let you adjust airflow direction or remove them entirely for maximum CFM. Installation is straightforward with the included mounting hardware and fits virtually any standard 14" x 14" RV roof vent hatch.
Aerodynamic dome profile sheds rain and redirects gusts away from the vent opening, keeping interior dry at highway speeds and in storms.
Integrated fine-mesh screen blocks mosquitoes, gnats, and flying insects without restricting airflow through the vent.
Formulated to resist UV degradation, fading, and brittleness -- critical for a component that lives on the roof year-round.
Adjustable louvers let you control airflow direction; remove them entirely for unrestricted ventilation on fair-weather days.
One of the most common complaints from RV owners is condensation and stuffiness during rainy travel days. This vent cover is specifically designed so you can safely leave the vent open during rain, allowing fresh air exchange without water intrusion. That is its primary job, and it does it well.
The 14" x 14" measurement refers to the vent hatch opening in the roof, not the outer dimensions of the cover itself. The Camco 40433 outer dimensions are approximately 19-5/16" L x 19" W x 8-11/16" H, which provides the coverage needed to seal around and over the standard 14" x 14" curb opening. Before ordering, measure your existing vent hatch opening -- if it is 14" x 14", this cover fits.
This cover is compatible with virtually all major OEM roof vents using that opening size, including Elixir, Jensen, and similar standard-footprint vents found on Forest River, Keystone, Coachmen, Gulf Stream, and many other brand RVs.
The 40433 installs from outside the RV and mounts directly over the existing vent hatch. No specialized tools required. The cover attaches to the vent lid or directly to the roof framing around the vent, depending on your specific hatch design. Mounting hardware is included in the box.
The 40433 is designed to be compatible with powered vent fans installed in the 14" x 14" opening, including popular units like the Fan-Tastic Vent and Maxxair Fan series. The dome provides enough clearance that the fan blades can still operate with the cover installed. Verify clearance for your specific fan model before ordering if you have an unusually tall fan assembly.
