P/N 80730 is for the 18.5" hinged SS grate. P/N 80728 is for the 22.5" hinged SS grate. P/N 90720 is for the SS O/T cleaning system for the 22.5". Sorry about the prices can't find them in my emails with weber. Just to check I placed them side by side with brand new plated versions and they are not as shiney so yeah there is a visual difference.
@demosthenes9 thanks man..really appreciate it
Whoops. Missed the SS part on the 18. 5all good man...have you thought about removing grill straps to make it easier to use standard grates on lower grate?.ss bolts with nuts will provide plenty of rack suppprtSent from my iPhone using Tapatalk
