TOODOO3 Pack Flying Insect Screen RV Furnace Vent Cover (2.8 Inch)(8.5 x 6 Inch) Stainless Steel Mesh with Installation Tool

I do like the sturdy design of the covers. They fit as expected. My only concern for opportunity is the installation. I have large hands and you will have a moment or two trying to get the springs lined up with the very limited space the spring allows. Recommend for any RV owner trying to keep the Wasps out.

When we first got our camper, I was told how important the screens are to put over the vents in order to keep dirt daubers from making their dirt clod nests in them. I searched online for these screens & guessed at the size because pretty much all of them were 8.5" x 6". The 2 small screens that go over the furnace vents fit perfect, however the screen for the hot water heater vent on our 5th wheel is much larger & the screen left a fair amount of the vent uncovered. I was able to find a larger screen (9.75" x 7.4") & it fits the water heater vent, but now we have an unused/unneeded 8.5" x 6" screen.

Easy to install

Measure carefully. I used the smaller screens with no problem. Larger one slightly too big for what I had in mind. ... my fault.Good quality

No installation instructions. Easy enough to figure out once you realize the spring only goes one way to properly hold/hook on RV vent side. Final installation wasn’t as tight as I would have expected. I added a bead of silicone sealer around outside to secure in place. Have taken RV on three road trips and no problems.

I wish it came with several extra springs, otherwise very good quality

They're easy to install and have been on there now for 3 months outside and no rust. Comes with the three springs or four springs to install and a little spring tool.

Works great on a dometic heater and water heater but the attached springs are a little flimsy. Use a piece of wire to secure it and it works even better. No more bugs coming inside the rv
