Antique Porcelain Lag Bolt Wire Hanger Insulator/Heavy Duty/10 Piece SET/Rare/Vintage

This is a rare, antique, 10 piece set of porcelain, lag-screw, wire-holder insulators. They are reinforced, heavy-duty, cable hangers used back in the day of knob & tube fuses. I believe they were meant for interior and exterior use. They measure approximately 4 inches in length from top to bottom with a 3 inch, lag bolt. These are commonly found in a more basic shape, but this type of unusual, circular, wire insulator hangers are not easily found especially not in such large numbers as posted here. Perhaps these have a craft purpose as well as their utility purpose. They are in very-good condition and being sold as a set only. Please be sure before purchasing as this item is NOT returnable.
