Here's a rarely seen and first offered on ICON CD 1175 Light Aqua substation plate insulator that held the glass bushing that covered the wires thru the wall. Unembossed. These are hard to find and huge!

Measures 16 3/8" X 1 1/2". This cd was only recently added to the NIA website. Excellent condition with some light wear in the glass bushing hole and light use marks. Easy VNM+.

First email gets this hard to find and rarely offered substation insulator for only $250 plus shipping. Thanks
