Product review (1 stars): Didn't need the part, but it was suggested to buy with the disposer
This was an item that was suggested needed to be purchased when we ordered our new garbage disposer. One came with the disposer, but wasn't clearly stated on the description. Got duped by the suggested additional purchases other People Also Purchased When Buying This Item. It was grouped together with the disposer as an Add this for X amount of dollars purchase at the bottom of the page. Too late to return, so I suppose we are left with a spare should we ever need one.
