I am involved in the programming stage of renovating a closed church to re-purpose it as an auditorium/lecture hall. I am trying to find an engineered product that will allow an electric projection screen case to be concealed behind an arch around 30' high and drop the entire case down to a usable height for viewing.
Preferably I'd like a packaged product, UL listed so I can provide cut sheets etc. to the architect and GC. All I've come across so far is a system made by screenite, who seem to be an Italian company. Not sure if they distribute in the US or if their product would be a match for my application.
