Product review (2 stars): EZ Mount groove too small for rubber gasket
So pretty and well made with brass.  Touted as made to fit EZ-mount disposals (Anaheim Manufacturing), the groove at the bottom of the throat for the clever rubber EZmount disposal gasket was too small on this flange.  I spent way to much time under my kitchen sink, fighting the disposal and the stupid ezmount rubber and mount ring.  I changed back to the disposal's included plastic flange with a large groove and the disposal installed easily.  I returned my warehouse deal Mr. Scrappy flange.
