This year, MCG Surge Protection celebrates its golden anniversary.  Over the past 50 years, MCG has evolved from a one-man operation in the garage of founder Michael J. Coyle’s three-bedroom ranch home on Long Island selling a small series of DC low voltage crowbars to a 14,000 square foot plant in Deer Park, NY.  

The company offers the widest range of AC Power Line, Data Line, DC and Low Voltage transient voltage surge protectors available. Designed and manufactured in the Deer Park facility to the industry’s most rugged specifications, we are proud to say that our products are of the highest quality and are proudly Made in America.
