Product review (1 stars): If You Want the Duckbill, Don't Buy This
Ordered the duckbill grommet, W10309238, received the drain tube extension: W10619951.  I have that part, wanted the duckbill as a backup in case the drain tube doesn't fit.  In any event, whether or not the W10619951 is the best solution, the vendor has engaged in a bait-and-switch.  I paid for something other than what I ordered.
