Product review (5 stars): A perfect fit
By measuring my dishwasher, I took a chance that these would fit according to the measurements.  They did.  Much better than the Whirlpool silverware basket that came with the dishwasher which was very narrow and did not hold much.
These are 3 pieces - I use one on the top shelf, and the other two below.  All of them fit fine and have much more space to hold more silverware.  Very pleased
