Keep your sink in ship-shape. Electro-plated stainless steel bottom grid with protective vinyl bumpers. Non-slip fit with rubber feet to keep your grid in place. This grid will come in handy to protect from chipping and damage that might occur if heavy cookware is dropped. The rubber feet can help to keep the glazed finish intact. Not recommended for other sink models as grid drain holes skew slightly toward the center, specifically for Vineyard Collection models.
