Our 3 in one disposal flange is a great addition for the cook in the family. Fits your standard 3 - 1/2-Inch sink opening, this strainer allows you to make a quick clean at the end of the cleaning. Simply lift the basket out and dispose of it neatly in the garbage for items that cannot be run through the disposal. This flange is designed to work with Insinkerator disposals. The stainless steel construction gives a great look with great durability and matches our Stainless steel sinks as well as flowing smoothly with our Silgranit II collection.
