This is an air intake screen for high efficiency furnaces and hot water heaters that use 3in PVC piping for the air intake. The end is tapered and should only need to be pressed in but could also be glued in with some silicone caulk.
Use this to keep the critters from making a home in your air intake. Depending on the material you use, you could also use this on the exhaust.
I also posted a 2" version.
