Product review (4 stars): Perfect Replacement Fit
Perfect fit for our dishwasher - model as noted as correct for our KitchenAid unit and it is identical to the original.  It seems slightly lighter in weight though, so maybe just a tiny bit thinner plastic.  It was not enough to make any difference in fit.  However - given that the original unit eventually gave way along the bottom after about 8 years (primarily where it rested immediately above the drying element), I expect this will probably do the same in a few years.
