Hello, I am replacing sections of cast iron in my house and i am curious what i should do to finish the stub out. since it is no hub, its not threaded, should I just transition the 2 in cast iron to a pvc stub with a fernco, or is there a better method? I wouldnt mind having the stub be CI, it would just feel like a more completed job. What is the recommended way to finish the drain line?

They are generally threaded. With a brass trap adapter screwed into them.

ah. mine is all hubless, how do i make that transition? i can find 1.5 brass arms but few options for connecting it into 2in CI
The trap arm is what goes into the trap adapter, which is in turn screwed into the sanitary tee.

Usually the trap arm that comes with the trap is long enough. While you can get brass P-traps, there is good advantage to getting plastic. The slip joint trap arm OD will be actual 1.5 inches or 1.25 inch OD for a lavatory. Slip joint traps are only for places that will remain accessible.

Transitioning to plastic pipe rather than going for an iron santee would make things easier.

This is awkward, but...
