Product review (5 stars): Fits Kindred Disposers!!!
This fit my Kindred Waste disposer (I had paid WAY TOO MUCH for a replacement about a year ago and it didn't last either) I would recommend this to anyone that is tired of overpriced replacement parts!  It was quite snug and I had to insert it using the stopper so it went in without any bends but it's working great!  Rubber on the original one didn't last and I think I'll be buying another one just to be sure I don't run out of them!
