I have a few Sediver multi-glass column station post insulators. It is an ANSI TR-216 type. It weighs 70 pounds, 30-inches tall, skirts are 8-inches diameter and there is 10 skirts, the top and bottom caps have a 3-inch bolt hole circle pattern, 4 holes- 1/2-inch N.C. threads. The glass color is ice aqua to clear and they have never been used. Rated at 69,000 volts, 350 Kv B.I.L. rating. This beautiful piece of glass can be yours for $140.00 plus shipping. Shipping will likely be done by LTL freight carrier due to weight restrictions by UPS and USPS, or you can pick it up if in the San Antonio TX area. Email me if interested. Thanks Tom.
