Grids for the KS-3218BL undermount stainless kitchen sink. Our high-quality stainless steel sink grids are custom made to fit each sink model. Sink grids help protect the sink surface from scratches and dents and add a food preparation area to the sink. Because the grid sits slightly higher than the bottom of the sink, remnant water is not able to contaminate food resting on it. Each grid has removable rubber feet and is dishwater safe.
