Product review (5 stars): Perfect! We purchased a new home and the disposer ...
Perfect!  We purchased a new home and the disposer sleeve was 17 years old and in really rough (and gross) shape. I searched the manufacturers website for the proper replacement part number, found this on Amazon and it fits perfectly.

Its surprising how quiet the disposer is now - shocking really. Looks much nicer and helps keep spoons and unwanted items out.
