Moen's production line does not differentiate between wholesale and retail models. There is only one grade of brass, only one grade of cartridge and only one grade of warranty coverage - the best. While the numbering system for Moen's wholesale distributors and retail distributors may vary and subtle installation and trim differences may exist. These may include, but are not limited to, packaging, threaded or slip-fit style tub spouts and metallic or non-metallic drain assemblies. The quality and limited lifetime warranty against leaks, drips, materials, and workmanship remain the same for all of our products.
