Hemingray Insulator Profile: CD 163  
This new style replaced the old, popular Hemingray - 19 (CD 162) in the 1940s. It was a more efficient design that used less glass. The CD 163 continued to be offered well into the 1960's, making it one of the last insulators with round drip points (RDP) to survive that late; most styles were replaced with corrugated base (CB) in the 1940's.
