Who We Are

The Duff Norton air jack line was first manufactured in 1929, and remains one of the most reliable lifting units on the market. The design has changed only subtly over the years, primarily to improve safety features and accessibility. In 2007, the air jack division was purchased and relocated from Charlotte, NC to Billings, MT. Over the near-decade since the company was relocated, the company has continued to make advances in the safety and reliability of the established products, as well as continue research and development to fit the customers’ specific needs.

The company now manufactures the bulk of their own parts in-house, providing their customers with the best lead times on parts and manufactured components. All of our qualified people pull together to insure the customer receives quality products with exceptional delivery times.
