Keeney’s flat-top kitchen sink strainer has a glass-friendly grid insert that protects glassware from tipping or breakage and prevents other unwanted items from falling into the strainer. It features an adjustable post basket with safety-rolled edges and a neoprene rubber stopper for secure connections. The post basket rests in two positions: upward for optimal water flow or downward to prevent drainage. The strainer’s stainless steel construction and high-quality design will help your sink endure daily use while protecting it from everyday debris. With three integrated thumb screws, it is easy to install and includes all necessary nuts and washers. You can install with confidence knowing that Keeney stands by its products with a Limited Warranty.
