Product review (5 stars): Perfect Replacement for My Disposal
Got this product for a Whirlaway 191 disposal.  Customer service for Whirlaway told me to order this specific product as a replacement and said it would work for all of their disposals.  My old splash guard wore out and did not fit properly in the drain any longer.  Anaheim Manufacturing makes both Waste King and Whirlaway disposals.  I got the product quickly and it was a reasonable price.  More importantly, it was a perfect fit.  If you need a replacement for these models, this is the one to order.
