That's not entirely true.
The regular Kettle has grate straps welded in, while the Outrider bowl has the formed ring to support the cooking grate.
The consequence of this is that the Outrider takes a slightly larger (17-7/8") grate that's not interchangeable with the regular Kettle or the modern Jumbo Joe.
You are absolutely correct! I should have used better wording.
I guess I was speaking in more general terms, specifically the shape of the bowl.
Thank you for the clarification.
