Our typical (Non-Seismic) installation above a ceiling is 8-1/2" to center of pipe. This allows us to use a 6" nipple and reducer to recessed heads. This normally requires a 1'-0" Min. space below duct work for elect, lights, sprinkler and support hangers for the duct work, since BOD will require an additional 1" to 3" for supports depending on size of duct
