Hemingray Insulator Profile: CD 196  
This large one-piece style, marketed as the "Perfect Transposition", is more commonly found with the H.G.Co. embossing (in stark contrast to CD 201). Transposition styles were used for swapping the positions of two lines. This would reduce the interference that would otherwise be caused by two lines running parallel to each other for too long a distance.
