Expanding Domestic Capacity for the Cable Systems that Keep America's Grid Running.

Marmon Utility, the Berkshire Hathaway company behind the Hendrix and Kerite cable brands, has been manufacturing in New England for 75 years, producing aerial and underground cable systems that power infrastructure across the country. When Marmon set out to expand its domestic manufacturing operations, RP Masiello was engaged to deliver two new manufacturing facilities at its Milford, New Hampshire campus.

RP Masiello completed construction on the first  building; an 80,000 sqft. manufacturing facility, which is already operational. Opened in August 2026,  the facility houses state-of-the-art production capabilities for Hendrix Aerial Cable Systems and new product solutions for electric transmission.

First Facility Complete and Operational. A Second Already Rising across the Milford Campus.

RPM is now underway on construction of the second facility, located across the Milford campus, and is scheduled for completion in 2027. Together, the two buildings represent a significant investment in American manufacturing capacity and in the infrastructure that carrys power to millions of American homes and businesses.
