Chebanse, IL.....
They're out of Benton Harbor MI. Their door has a "cam action" roller at the top that enables the cylinders to constantly push UP, vs out as in most hydro doors we've seen. This (per their statements) enables them to open/close a 40'+ door in less than 45 seconds with a 3 hp pump. So, does anyone have one...or know of one?
They've got a pretty good interactive website w/videos.
