C-Line Products was founded in 1948 in Des Plaines, Illinois, just outside Chicago, as a manufacturer of plastic office supply products.

C-Line has maintained its Des Plaines manufacturing for over 75 years — an unusual commitment in a category where most competitors moved production to Asia in the 1990s.
