This Ventline Ventadome roof vent keeps air moving inside while the trailer stays locked up tight. The hand-crank dome opens easily from the inside to let in fresh air and push out heat or humidity. There’s no wiring or switches needed—just turn the crank to open or close it. The translucent white polypropylene cover lets some light through, brightening the space without direct sunlight.
The aerodynamic, wedge-shaped dome is made from tough polypropylene that stands up to weather and road wear. Underneath, the galvanized steel flange won’t rust or corrode, even in damp conditions. The result is a vent that holds up to years of use and keeps its seal tight against the roof.

This vent fits the standard 14-1/4" wide x 14-1/4" long opening found in most setups, so replacing an old vent is simple. The included Birch White interior garnish fits roof thicknesses from 1-7/8" to 3" and gives the inside a clean, finished look. When closed, the vent sits 4-1/2" above the roof and opens up to 10-3/4" for full ventilation.
Maintenance is quick thanks to the removable screen. It snaps out for cleaning and pops back in without tools, so you can keep bugs and dust out while still getting good airflow.
Mounting is straightforward with the proper installation kit. Apply sealant around the galvanized flange, drop the vent into place, and secure it with #8 screws. Pair it with the Roof Vent Installation Kit # 344270KITW, which includes the screws and sealer needed for a watertight setup.

You can switch out the ceiling garnish for a taller one like with part # VA0445-37 which is 5.31 inches tall. It can be trimmed down if it is too tall.
Do you have a question about this RV Vents and Fan?
