Wells Sinkware's custom designed bottom grids are made specifically for each of their sinks. Made of high grade stainless steel, they help protect the sink bottom while serving as a handy straining tool when washing dishes or preparing food. The grids sit on protective vinyl feet to keep from scratching up the sink bottom. The durable stainless steel will hold up over time with the same reliability that Wells' sinks are known for. This model fits the large bowls in Wells' WL-KS2364, WL-KS2366 and WL-KS2382 sinks.
