Since 1965, Harbour Industries has been manufacturing high temperature and high performance cable for the military, commercial, and industrial markets.
During the late 1960's and early 1970's, a number of plant expansions took place in order to service the growth of the Aerospace Market. In 1975, an additional manufacturing facility was established in Farnham, Quebec, Canada.
In the 1980's and 1990's, new Mil-Spec cables and RF Microwave cables were added to Harbour's product offering. In 1994, Harbour became a member of the Marmon Group an international association of more than 125 autonomous companies based in Chicago, Illinois with collective sales exceeding $6 billion.
Today, Marmon Wire & Cable LLC includes more than 12 member companies that manufacture and market electrical and electronic wire and cable. Together, these companies have annual sales of approximately $1 billion and employ approximately 2,300 people in North America and in Europe.
