Essential product for every RVer!
Reviewed in the United States on July 31, 2017
These are one of the first things I do to a travel trailer after purchasing a new one. I have seen many RV furnaces clogged and filled with mud dauber nests, particularly in the spring when they are looking for a place to call home. Not only does this make your furnace inefficient, it is extremely dangerous, as the heat can cause the nests to catch fire, burning down your home away from.
To install them, mount the included springs to the screen, and place the slotted tool through a hole in the screen, and stretch the spring around one of the metal bars on the furnace vent. Takes no more than a minute or two to install and protect your RV furnace from uninvited guests.
One note, these only fit Suburban and Duo-Therm furnace vents. If you have an Atwood furnace, you will need a different screen, which is also available right here on Amazon. Double-check your furnace manufacturer to make sure which you have before ordering.
