Product review (3 stars): It wan;t needed-so I sent it back to Amazon
Reviews of the installation materials supplied by Amazon and Waste King and several reviewers led me to believe this adapter kit would be helpful in installing a new Waste King garbage disposer.  When I opened the garbage disposer package, I could see that I had everything I needed to install the new device so I arranged to send back the Waste King 3101 ISE Adapter Kit and got a refund.  I had to pay for shipping so my mistake only cost me some of my time and about $5 in shipping cost.
