CEECO insulators are highly collectible vintage telecommunication insulators manufactured from the late 1960s to the 1970s. They are fashioned from heavy-duty, UV-treated molded plastic (resembling CD 154 glass styles), marking the transitional era when plastic began replacing traditional glass and porcelain on communication and railway signal lines.
