The OATEY K820-33 is a mesh kitchen strainer basket designed to fit standard kitchen sink drain openings. It captures food debris and solid waste before they enter the drain line, helping prevent clogs and protecting downstream plumbing. The basket is intended for residential kitchen sink applications and is typically installed or replaced by plumbers or homeowners during routine sink maintenance. Its mesh construction allows water to flow freely while retaining debris for easy disposal.
The K820-33 is suited for use in residential kitchen sinks where a standard strainer basket is required. It serves as a direct drop-in replacement for worn, corroded, or missing strainer baskets in common sink drain assemblies. The compact profile fits within standard drain cup housings without modification.
Designed as an OEM-style replacement strainer basket for standard residential kitchen sink drain assemblies.
Installation of a strainer basket typically requires no tools and no licensed trade credential. Shut off water supply to the sink as a precaution before servicing the drain assembly. Remove the old basket, clean the drain cup housing of any buildup, and drop the new basket into place. Ensure the basket seats properly in the drain cup before returning the sink to service.
