s. To give an overview of the large variety of styles produced, the following table contains the twenty most common. The table provides two numbers: the Consolidated Design (CD) number and the style number. The CD number is from a classification system developed by collectors that refers to the shape of the insulator, and is independent of the Hemingray Glass Company. However, the style number (or name) was assigned by Hemingray to each insulator. Due to slight modifications in design over years of production, single styles can span multiple CD numbers.
