This is a very common Hemingray pony style insulator that replaced the earlier CD 106. This design was chosen to replace the popular CD 106 because it used less glass and was generally considered more robust.

Note: The insulators a free of any major cracks but might have some minor nicks/chips.

Use this insulator with my indoor lamp base or my low voltage landscape light base.

  • Glass Insulators

    Glass insulators were first produced in the 1850's for use with telegraph lines. As technology developed insulators were needed for telephone lines, electric power lines, and other applications. In the mid 1960's a few people began collecting these antique glass insulators. Today there are over 3,000 insulator collectors.


    All glass pintype insulators are classified in what is called the “CD Numbering” system of identification. This system was created and used by N.R. “Woody” Woodward, an early pioneer, researcher and author in the field of collecting glass insulators. The CD (Consolidated Design) numbers basically identify insulators by their shape and profile, regardless of exact embossed markings, glass color, or base type.
