A: A few north area do require higher vent pipes. National code is min 6" but most local codes require 12", the Perma Boot will work for both of those situations. The only places that I know requiring greater than 12" are Erie, PA and Massachusetts
A: Squirrels don't seem to eat the plastic Perma Boot. They like lead because it has a sweet taste to it
A: It's the inside diameter as is said right in the description of the product at the top of the web page "Pipe Boot for 2 in. I.D. Vent Pipe Black Color New Construction/Reroof" Maybe read the full page before asking questions? Just a thought.
A: The inner diameter is 2 inches.
