About S&D Products

For over 50 years we've been hinging our business on your business.  Whether you need 1 hinge or 1 million hinges, we are here to service you.   We've grown from a small company in Bensenville, IL to our current 125,000+ sq ft facility built in Bartlett, IL in 2009.   John & Kathleen Guanci started S&D Products in 1957.  David Guanci carried it on, making hinges and branching into metal stamping and laser cutting services.

Today, Mark Guanci and a team of professionals continues that tradition of manufacturing excellence with personal service as we continue to service both small and large businesses worldwide.   We truly believe that our business hinges on your business.
