Leadership & History

Our History

Lone Star Industrial was founded in 1977 by brothers Ralph and Bob Navar. Their mechanical background stretches back to their childhood days when they installed a refrigeration system and engine in an old Flyer wagon. They were able to foresee the need for test equipment, including accessories, in the wire harness industry. As changes occurred within the industry, Lone Star Industrial (LSI) began manufacturing spring-tested pins to accommodate specialized fixtures. LSI has continued to adapt to the needs of the wiring harness manufacturing industry with innovative and redefined products.




Ralph Navar

Founder and First President

Ralph Navar, Jr., one of the original founders and president of Lone Star Industrial has been creating and engineering since his childhood. He has designed a variety of projects to help his family business. However, with a fascination with aviation as a teenager, he began building full-size aircraft. Ralph was inducted into the El Paso Aviation Association Hall of Fame for his work on a variety of projects and devices to modify aircraft to allow people with disabilities to fly their own aircraft.
In 2014, Ralph decided to spend more time with his two loves, his wife Carolyne, and aviation.
