Camco Flying Insect Screen for 2004 Atwood - Keep Your RV Furnace Safe from Insects & Rodents - Heavy Duty Stainless Steel Construction - RV Furnace Vent Cover with 3.6" Diameter (42144)

This was exactly what I needed, but the sellers size description is wrong. It is 4 7/8 (4.875) inches in diameter, not 4.6 inches. See photo for reference.

I was not exactly sure how to install this, but happily, the manufacturer printed instructions on the back of the cardboard flap that seals the bag shut. This just slips into place. You will not need any zip ties or anything. The housing for the vent cover also holds the screen securely in place. I would recommend this.

If you want to keep the wasps out of your refridgerator unit, these do the trick. A little tedious to install, but when done, they work.

It keeps bugs and other critters from getting in the refrigerator

The screen is great, keeps the bugs out as advertised. The springs to hold it in place suck, they don't work, allows the screen to move around and they finally break. I went to A e hardware and bought a small spool of stainless steel wire and laced the four corners.Now it doesn't move at all and the SS wire won't show rust.

fit perfect.Suggest you use 4 wire ties for each screen as opposed to the 3 per screen that are supplied.

Slightly too big but I shoved them in there. I feel it's kind of ridiculous they only give you 2 zip ties to use for each grate. It needs for sure 3 zips per grate so you can have a zip in the middle. Classic skimp on a product that we already overpaid for (this thing probably cost $2 for the manufacturer to make, if that). I wish the ends of these were not curved because as you can see in my photos and from tons of other reviewers, that curve leaves a hole big enough for a wasp or whatever to get in there. Why make it curved?! I'm going to leave mine here and see how they do. They cover 98% of the gap so it'll do for now.

Bought for hot water heater but should have measured since it didn't fit.

These bug screens were the perfect size for my Norcold RV refrigerator vents. No need to cut to size. Installation was easy enough with the six zip ties provided. I would have liked a few more zip ties to ensure a snug fit as there are some visible gaps where they don't lie flat to the screen. I may add my own in the future. It would also have been nice if they came in black but I plan on spray painting the screens and cover with rustproof paint to ensure the longevity of the screens. Overall, I'm pleased with these screens and their ability to keep wasps and other critters out of the back of the refrigerator space.

Super

Screen on our RV furnace outlet. As all of the other brands etc. in this lineup the springs are quite useless. If you use the spring attachments eventually lose the screen. I attached ours to the side of the trailer with mirror clips (angles) that fit perfectly after I cut the side just enough to allow the clip to fit through and screwed them onto the side of the trailer with the small crews included with the clips, guaranteed not to come off. As for any damage to the trailer from the screws there is none as the are covered by the clip. There ,problem solved> This screen is one of the best I came across and would buy again.

We’ve had on our trailer for 2 years now and it has been solid. It hasn’t come off or moved once, and it’s done it’s job. Definitely recommend for piece of mind.

Les ressorts etaient trop long . J ai modifie le systeme et c est parfait
