Wasps and mud daubers love building nests inside RV water heater vents, and a blocked vent can cause serious damage by restricting airflow. This screen fits over the vent opening on Suburban 10, 12, and 16 gallon water heaters to keep insects out.
It's made from heavy-duty stainless steel mesh so it holds up to weather and road vibration, and it installs quickly with the included tool.
Cheap insurance against a clogged vent and a much bigger repair bill down the road.
