Product review (5 stars): 3101 ISE Adapter
Nice quality adapter to convert a non ISE disposer to the higher quality ISE drain.  I put this on a Whirlaway 291 Disposer because I did not want to remove my existing In-Sink-Erator drain, when I replaced my rusted out 26 year old Badger Disposer.  I also did not like the cheap plastic drain that came with the Whiraway.
