Product review (4 stars): Pricey but work fine
Works great on the majority of dishwashers with wood or Formica counter tops.  Only reason for four stars is price, you need two and this is a price for one without screws.  If you're buying these, you likely don't have the accessories from the dishwasher so you need to find screws that fit.  Fortunately, 3/4" #10 sheet metal screws from WalMart will usually work fine.
