I picked up a couple of the same brand there EARLY this year that were for kettles & also clearanced. It was only after I got home that I realized they were also only 30" tall, so I figured I'd have to be a leg man.
Then I decided to use one on my old 18" Outrider (old style Jumbo Joe). Another I'm going to see if it will work on my Weber fireplace because they were supposedly up to 28 or 30 diameter. When I set up my 26" brownier, that will be it's cover at least temporarily.
