Product review (5 stars): Problem solved
We have an undercounter dishwasher, 10 years old.  Counter is granite.  I had epoxyed it 9 yrs ago and it lasted.  We tried again with several different epoxys this yr but none lasted.  I think more force is now needed to close the dishwasher as the latch is stiffer than it was 10 yrs ago.  Anyway,  my husband found these on line and he installed them - took maybe 15 minutes.  We held them in place lightly with C clamps for 24 hrs and it has been several weeks and so far so good - finally!  This was an inexpensive, easy, and not messy fix.
