Hemingray Insulator Profile: CD 190/191  
Hemingray manufactured this popular two-piece transposition style insulator. 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. Hemingray also manufactured these for Am. Tel. & Tel. Co.
