This listing is for a vintage brass chandelier ceiling light canopy & center connector rod.  It measures 5 1/4" across the ceiling fitter end and is 4" long.  The threads measure 1/2" across.   There are scuffs, scratches, 2 or 3 small dents and some paint around the edges on this from over the years.  It is a nice piece from a nice estate.  Thanks for looking!
