Product review (2 stars): the pulley studs snap off rather easily providing a nice stream of income for them on ...
Was one of several parts purchased before the Kitchenaid (Whirlpool) dishwasher completely failed after less than 3 years.  I will wash my clothes and dishes in a creek before I buy another Whirlpool product, -total junk.  And, it wasn't first one of these rack adjusters I had to buy either, the pulley studs snap off rather easily providing a nice stream of income for them on replacement parts.  Save the added expense/frustration and admit to yourself now that buying their product was a mistake and replace it outright with something more reliable.
