Finally Got My Garage Mahal!!! in Shop Talk Posted December 25, 2021 I would definitely feel more comfortable with it bolted down. I am always a little hesitant to pass underneath it and always check all 4 locking latches after setting it in place. From a mechanical standpoint; without being secured, based on the post and crossbar design, I doubt it could fail in the fore and aft direction. I do think with some coercion it could fail in the side to side direction with a heavy load. It would be an interesting, albeit expensive, experiment to see what it would take to fail.
