Product review (3 stars): I have nine and a half dozen left over if you want them!
They certainly do the job... but who needs ten dozen?  As far as I can tell these will fit any dishwasher's rack pins.  I used clear RTV under them to make sure I had a watertight seal, although they are incredibly tight going on anyway.  It is just silly that you have to buy so many in a package.  I mean they are cheap enough but geeze.  Perhaps if I were in the dish machine repair business...
