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 basket strainers are designed to keep the unwanted bits of food and junk from washing down the drain and clogging the pipes. The basket collects particles and is easily removable for sending them to the trash.
