Stainless steel mesh screens that slip over exterior RV refrigerator vent louvers to block wasps, mud daubers, birds, and rodents before they nest and cause overheating damage. Fits 19-3/4" louver openings including Norcold refrigerators. Three screens per pack. Does NOT fit Dometic refrigerator vents.
Wasps and mud daubers are drawn to the warm air exhausting from RV refrigerator vent openings. Left unchecked, they pack the vent cavity with mud nests and debris that block airflow, force the cooling unit to overheat, and can result in costly refrigerator failure -- or a fire hazard in the vent compartment. The Camco 42148 RS500 is a direct, low-cost defense against that risk.
Each screen is formed from fine stainless steel mesh stretched over a rigid frame sized to cover the horizontal louver slots on a standard RV refrigerator vent panel. Installation takes minutes and requires no tools on most vent styles -- the screens press or clip into the louver openings from the outside.
Corrosion-resistant woven wire mesh that holds up to road vibration, rain, and UV exposure without rusting or sagging.
Covers both upper and lower refrigerator vent openings on a typical two-vent installation with a spare for future use.
Designed to press into the louver slots of compatible vent panels without drilling, cutting, or adhesive on most installations.
Sized specifically for 19-3/4" Norcold refrigerator vent louver openings and most other brand refrigerator vents of the same dimension.
Mud dauber and wasp nests in refrigerator vent cavities are one of the leading causes of RV refrigerator overheating failures. A single season of neglect can result in blocked burner flues, failed cooling units, and voided warranties. Installing vent screens is a five-minute preventive step that costs a fraction of a service call.
The Camco 42148 is designed for refrigerator vent louver openings that measure 19-3/4" wide with a slot height of approximately 1-5/16". This dimension matches the standard vent panels found on many Norcold refrigerator models and other non-Dometic RV refrigerators using the same vent panel format.
The 42148 does NOT fit Dometic refrigerator vents. Dometic refrigerators require a different screen size. Check the Camco lineup for the correct Dometic-compatible part before ordering.
On most compatible vent panels, each screen slides or presses into the louver slots from the exterior side of the rig. No drilling is required. Screens should seat flush against the louver opening so insects cannot enter around the edges. Check the fit of each screen after installation and re-seat if gaps are visible.
Before your first trip each season, remove the vent screens and clear out any accumulated debris, insect eggs, or old nest fragments from the vent cavity. Reinstall the screens and confirm the refrigerator vents are drawing air freely before loading food and heading out.
