Dubuque

Tucked away in Dubuque's North End, Iowa USA,  in a building that once housed a furniture and casket company, is a small niche business that has been an industry leader for decades.

For roughly 40 years Keith Clark has owned and operated Dubuque Clamp Works, which manufactures specialized clamps of all kinds.

Clark, a former John Deere Dubuque Works employee, runs the small business with his wife, Edna.

The company produces approximately $500,000 worth of clamps annually and has clients both large and small all over the country, including familiar names like Craftsman tools and Gibson guitars.

The company's clamps regularly are featured in trade publications in the USA.
