LINE AND STRAIN INSULATOR IS ALSO CAR-STOP SIGN

 

A line and strain insulator, used to guy trolley wires, has been designed so that it may also be utilized as a car-stop sign. The insulator is made of similar material to that found in high-voltage insulators, and has black lettering upon a highly glazed white surface to which soot or dust does not readily adhere.
