Product review (2 stars): you would have the metal adaptor that comes with Insinkerator garbage disposals). I purchased an Elkay stainless steel sink ...
The description of this adapter kit is insufficient. It does not contain all of the parts needed to install, but assumes that you are removing an Insinkerator (in which case, you would have the metal adaptor that comes with Insinkerator garbage disposals). I purchased an Elkay stainless steel sink from Home Depot that (unbeknownst to me) had been created to only work with an Insinkerator garbage disposal. The Elkay sink description also did not include this information in the on-line description. When the plumber arrived to install the new Waste King garbage disposal on the new sink--he could not complete the installation because we were missing the metal adaptor. I called Waste King customer service and explained my situation, seeking an adaptor and was pointed to this Waste King 3101 ISE Adaptor Kit, which I purchased. Even the customer service person did not know that the adapter kit did not contain all of the necessary parts for the installation. This mix-up resulted in three trips for the plumber and much wasted time. One cannot be an expert on all things, and it is disappointing to discover that those who ARE experts fail so completely to communicate.
