PVC Termination Cap Mesh Screen Vent Cover, Furnace & Roof Vent Cap, Stainless Steel Wire Round Exhaust Pipe Cover End 2" Inner & 2-3/8" Outer Diameter

This wire mesh cap was used for my HVAC intake pipe, which previously allowed birds to get inside. I did need to sand the cap down to fit into my 2" pipe, but this was stated right in the listing. I appreciate that it has a good friction fit and the wire mesh seem quite solid, so this gets 5 out of 5 from me.

Last year a bird made her nest in my heating pipe. During the summer, I cover the pipe with this item.It looks good, is easy to install and is very functional. No more nests!

Had to update my dryer hot air exhaust run. From a windowless basement, going up the wall and across the 2nd story crawl space. Last jerry-rigged solution slipped off the round metal duct and allowed a bullfrog or two to move in and cause problems. This solution is working. The sequence consists of a large hole cement block, a 4" PVC conduit pipe coupler jammed inside it, the aluminum round duct stuck into the coupler and this PVC stainless mesh cap inserted into the other end (terminal) of the coupler. Added a string to be able to pull it out. It is actually a 4 inch OD.

Exactly what I needed

Very Good

It’s perfectly fit for my outlet gas pipe connection

I am using NDS sewer & drain 4" PVC pipe for ERV ducting. This is not SCH40 pipe but thinner wall sewer & drain pipe and fittings. This 4" screen fits inside an NDS hub by using a heat gun to soften the hub. It is not easy and it took me about an hour to achieve but it has worked out very neatly in the end, see photo. Once the hub is very warm / too hot to touch, I forced the screen (which has a solid pvc collar) into the hub perpendicularly to expand the hub while rotating it to expand the hub evenly all around. Repeating the heat and expand procedure many times eventually allows the screen into the hub. Once it is slightly inside evenly all around, it is much easier to continue heating and press it in all the way.This long turn elbow will be pointing downwards on the fresh air intake. I will not glue the elbow to the pipe so that the elbow can be easily removed for cleaning. I can reach the inside side of the screen through the removed elbow. Therefore it's fine that the screen is now stuck permanently in the hub just through friction with the warmed pvc.I have bought several of these screens in the past for air intakes and very happy with their quality and longevity. I point them down on air intakes where I can easily see and vacuum them every now and again. No screen on exhaust provided exhaust is in regular daily use to expel the bugs. In my case the ERV will be on 24x7.If PVC is in direct sunlight it needs to be painted to protect from UV.I don't know if the 3" size fits inside a 3" NDS hub but it's worth a shot.

Perfect fit and ideally suited to prevent rodents from entering the exhaust pipes from the furnace and hot water heater.
