A: What you likely need is a plug for 2" pipe. This one here has a different style thread on it and it's designed for that black part to fit on the end of the bare ABS pipe (or it may go into a female fitting, hard to tell from the pic here). Thread diameter on your replacement should be 2-5/16", or very close to your measurement of 2-1/4", but they will likely still refer to it as a 2" plug. Hope this helps someone.
A: This plug is designed to seal off the inside diameter of the pipe itself not the threaded fitting. It wont take the place of the threaded plug. They do have inexpensive pvc threaded plugs you can buy.
A: This plug has a minimum diameter of 2.05 in. and a maximum diameter of 2.07 in. Your remaining question cannot be answered at this time.
