Product review (1 stars): Just Buy Black Foamboard at a Craft Store!!!
So it is borderline criminal to be charging $40 for a $0.05 piece of plastic but you're going to pay a lot more if you buy this part from anyone else.

But what really bothered me was that this part didn't come with any screws, washers, or nuts. And worse is that the pre-drilled didn't quite match up with my Kitchen-Aid dishwasher. So given that you will likely have to drill new holes and supply your own hardware, you're probably better off just buying a section of black foamboard or plexiglass and saving yourself $40.
