Vintage Bronze Post Outlet Steel City Electric Co. PA. Device Box

The part has an old dark brown receptacle installed at the moment. It has a 2 7/16 inches long post on the bottom that has a 7/8 inches outside diameter with a coarse thread on the outside. The box measuring from the back is 3 15/16 inches wide and 2 5/16 inches tall not including the conduit. We removed the faceplate and did not find anything inside attached to the receptacle. It is heavy at 1 1/2 pounds prior to shipping materials and a sturdy box. Please study photos as they are part of the item description and it is not perfect. We are selling as found and it has not been cleaned or polished.
