I have a 3" wide opening. the 2 inch looks too small and the 3 inch looks too big. what size do i get?

These fit into the 3” pvc fitting that about 3 3/8”. Your vent maybe 2 1/2” that was very popular 15 yrs ago. Pvc is measured inside diameter.

Will this snugly fit over the metal 4 in. furnace vent ( e.g. galvanized Quick Fit Duct, 4" , female smooth end)

I’m not sure. I wish I could include a picture. Ours went just inside of pvc piping that is venting something from our basement and the fit was perfect inside the pipe.

I have a 4" outer diameter pcv exhaust vent. will the 4" cap fit or should i order the 3" since the inner diameter is approx 3.5"? thx.

I'm not exactly sure but I had a 2" inch pvc pipe and I ordered the 2" screen. Hope that helps. Whatever the pipe is listed as, buy the vent the same size. 4" pipe 4" vent.

what is the spacing measurement on the mesh screen (size of the squares) ? Thank You!

0.4 inch - Please click on the "click more images" to enlarge and you will see the 8th image on the right side showing the spacing of the square close-up with zoom.

Worked fine. Good quality.

Worked fine. Used to replace a cowl end that was very restrictive on the roof. Used a rubber coupler found at bunnings hardware in Australia to attach.

Big Improvement

Needed a little sanding to fit. I chose NOT to glue it and make it permanent. Used a couple of screws to keep in place and now its removable. Keeps the bees and rodents out. So much better than the plastic screen from the big box stores. Would buy again.
