Wasps, mud daubers, and rodents love the warm, sheltered space behind your RV refrigerator vent -- and their nests can block combustion airflow and create serious fire and CO hazards. The Camco 42156 installs over the exterior vent opening to stop pests before they get inside, without meaningfully restricting the airflow your propane fridge depends on.
This screen is sized specifically for the exterior rough opening found on many Norcold RV refrigerators -- 6-3/16" x 17-13/16". Unlike universal cut-to-fit mesh, the 42156 installs cleanly without trimming or guesswork. The heavy-duty stainless steel construction resists rust, UV degradation, and attempts by small rodents to chew or push through.
Mud dauber wasps are the number-one pest threat to RV propane refrigerators. They can build a blocking nest in a single camping trip, and a clogged flue is not always obvious until the fridge stops cooling or a CO detector trips. Installing a proper insect screen is one of the lowest-cost, highest-impact maintenance steps any RV owner can take.
Sized for the 6-3/16" x 17-13/16" rough opening on compatible Norcold refrigerator vent panels -- no cutting required.
Corrosion-resistant stainless mesh stands up to road vibration, weather, and persistent pests season after season.
Mesh gauge is fine enough to stop insects and rodents while allowing the combustion and convection airflow a propane/electric fridge requires.
Lightweight at 0.4 lbs and designed for tool-minimal fitting to the exterior vent opening. Sold individually.
Norcold absorption refrigerators (and most other RV propane fridges) rely on a continuous chimney draft to remove combustion gases and heat. When mud daubers, paper wasps, or rodents build nests in the lower or upper vent cavities, that draft is disrupted. Consequences range from poor cooling performance to dangerous carbon monoxide buildup inside the coach. Preventative screening is far easier than cleaning a hardened mud nest out of a burner flue mid-trip.
This screen is designed for Norcold refrigerator models that use an exterior vent rough opening measuring 6-3/16" x 17-13/16". Before ordering, measure your existing vent opening. Camco offers additional insect screen sizes and configurations in the 42140 series for Dometic and other refrigerator brands -- confirm the opening dimension matches before purchase.
