Product review (1 stars): Waste of money
I could not figure out how to attach the disposer to the sink flange with this adapter.  I assumed it was just my ignorance till I called the help number in the instructions.  What a supprise.  The help person didn't know how to install the darn thing either.  Even if this adapter would work, you don't need it. It's a lot easier to follow the instructions that comes with the disposer.
