Product review (4 stars): Perfect Whirlpool replacement part
This replacement part fit perfectly in our 5 year old whirlpool dish washer.  After reviewing a few YouTube install videos before purchasing the part, it took 15 minutes even for a non handy girl to replace  both sides of the top dish washer tray after the part was delivered. Would like to give it 5 stars but the  part is plastic and will eventually  wear out again.
