Copperweld Lightening Rod

Stonework at the Frank House recently revealed a link to the home’s historic heritage and Pittsburgh’s industrial past. Stonemasons set a new capstone on one of the home’s chimneys, fitting it around a lightning rod connected to a grounding cable. The connector was invented by Robert Frank, and the lightning rod, connector and grounding cable were made by Copperweld, the highly successful steel company that he built.
