I recently bought several Atlas Switch Control Boxes on eBay. None had the screws for wiring or the connectors that join boxes together. I understand that Atlas does not sell these items separately. Does anyone know where to get similar items?
I just tried a 2-56 (to small) and a 4-40 (to large) in a control box so I would bet they are metric, probable a 2 or 3 mm.
