Product review (1 stars): Don't Buy....These don't last. Buy the NEW metal parts (W10712394) instead.
I bought these to replace my original ones that broke only after a year. However, these aftermarket replacement didn't even last a year. Fortunately,  a new metal parts are now available that are supposed to fix this recurring problem.  The new part number is  W10712394.  It fits various brands of dishwashers that used part W10350376.
