Renold Jeffrey has over 100 years of tradition in engineering expertise, system design, and problem solving. Not only does Renold Jeffrey provide quality chain products and accessories, but also immediate and accessible technical assistance for our customers. The complete line of conveying, elevating, and drive chain at Renold Jeffrey today is the result of years of research and development. With many sizes available - each style designed to fit a specific need - it is never necessary to compromise a particular chain selection.

The 200, 000 square foot facility accommodates the expansive, modern manufacturing plant, the well-equipped research and development laboratory, and the staff offices. We also have our National Sales Center in Hebron, Kentucky serving as our distribution center for all roller chain and attachment chain products.
