Product review (3 stars): Wrong part labeled as WD28X21715
The item received did not match GE OEM part number WD28X21715. Instead the item with this label appears to be associated with a rack of another unit that separates the lower comb assembly (metal prongs that hold plates) from the lower rack assembly. Had I received the comb assembly, wheels and clips to connect everything I'm sure this would have been a 5 star review.

While I didn't test the rack, the quality appeared to be in line with OEM standard from initial inspection.
