I'm running into several situations where we are having to do creative things to make plenums for louvers and on top of air handlers. It would be nice to be able to create an actual plenum that you could connect ducts to. I know you can just make a big duct but you are limited to connecting to it from the sides top and bottom. I am talking about just making a sheet metal box that is completely enclosed on all sides and then you can tap into it with ducts from all sides. Would be handy if you could also make custom shaped plenums (i.e. plenums for sets of louvers that have to be custom made to wrap around structural elements).
