This is the kind that is trapped between two cross arm with a large hole for the wide post. Hemingray-12 from the other ad is to give an idea of the size. Nearly black with charcoal and a few color highlights and no markings. It is as near a mint piece as a service used insulator can be. Asking $18 plus shipping. It is as heavy as a brick or small mulitpart. I'll try to ship the most economic way possible. Continental U.S. only. Thanks for looking.
