    The description says this part is for Weber genesis side burner grills. I have one of those so ordered it. Unfortunately, it does not fit my side burner grills when I contacted customer support, they were not helpful saying the description states multiple times it only fits certain side burner grills the description does not say that and if it did, it should say which model numbers they fit.
