3 1/2" kitchen sink drains and garbage disposal flanges. Made to fit most kitchen sinks.
Most kitchen sinks have either one or two wells for food preparation and washing dishes. Kitchen sinks like stainless steel farmhouse sinks typically have one large well, and require only one sink drain. Other sinks, such as stainless steel undermount sinks, may have two or even three wells, and can use a garbage disposer flange in addition to a standard basket strainer. Other kitchen sink accessories include stainless steel sink grids, cutting boards, and even colanders.
