That's what I think too. Sometimes you see grills at hotels or resorts that are set out for guests to use. I wonder if these stationary grills were intended for that purpose more than a home outside kitchen application. I can't see building that grill into a stone or brick enclosure where you still need access to the slide out grease tray.Yah, I am pretty sure they were intended to be staitionary grills that bold down to wood decks or even anchored into a concrete pad.
Edit: I wonder if there is any mention of these grills in some of the old catalogs.
