The doors look really cool. I bet it is very satisfying to watch them open and close.

I’m not usually one of those safety hounds but those doors are huge. I hope there is some kind of device on those lift cylinders that prevents them from collapsing if there is a sudden loss of hydraulic pressure. You sure wouldn't want to be standing in the doorway if they ever came down fast.

They sure look a lot better than a steel roll-up door, and I would think they seal up better than a sliding door too.
