The Durham Company was founded and organized in 1959 by Roy Durham in Washington, Mo. Durham was a leading design engineer with the Binkley utility division of Binkley Manufacturing Company. The company s initial products were meter sockets, polyphase enclosures and test blocks for the electric utility industry. Through the 1960s, the product line was expanded to include combination socket/breaker and socket/transfer switch units for the farmstead. By the early 1970s, it was a significant supplier to regional investor-owned utilities. During this time, it also was a major supplier to the Midwest rural electric cooperatives and electric municipalities. Product design and development of pad mount equipment started in the 1980s.
