How to Keep Insects out of my Camper's Refrigerator and Furnace Vents.


My 2019 travel trailer has a Norcold refrigerator model # N412.3 Full and a Suburban furnace model # NT-20 SQ. I am interested in dirt dauber screening to protect the items from nesting. Please contact me with your recommendations.

For your furnace I was able to locate some pictures of it and it appears to use a dual round outlet. In that case use the Valterra Bug Screens for Suburban and Duo-Therm RV Furnace Vents part # A10-1301VP.

For your refrigerator I have a couple sizes of the Valterra Bug Screens for Norcold RV Refrigerator Vents unfortunately I was unable to confirm the exact one for you. I have listed them here for you and their dimensions for you to pick the appropriate one.

Part # A10-1312VP has three covers and they measure 27.5" x 1.3"

Part # A10-1310VP has three covers and they measure 19.6 x 1.3"

Part # A10-1314VP is a single cover and measures 17.5" x 5.87"
