Thank you for viewing. This is the upper basket only for a Rinnai built-in dishwasher. It is the upper basket specifically for model RKW402L, and is used by inserting the holes of the upper basket into the protrusions of the lower basket. It is unknown if it fits other models. This is the upper basket for RKW-402L. *This basket is used for setting teacups and glasses. I checked it for the listing. There are no warps, paint peeling, or rust. *Please refrain from purchasing if you are concerned as it is a used item. *Instruction manual is not included. It will be placed in a new bag and shipped in a recycled cardboard box.
