Wells Sinkware's custom-designed bottom grids are made specifically for each Wells sink, so they'll fit your model perfectly. All the better to protect their satiny finishes from the abuse of daily use. Made of high grade stainless steel, they also are handy as strainers when washing dishes or preparing food. The grids sit on protective vinyl feet to avoid scratching the sink bottom. This model fits the large bowl in Wells' WL-KS2370, WL-KS2372, WL-KS2371, WL-KS2373, WL-KS2383 and WL-KS2384 kitchen sinks.
