The Belt Line Industrial Park has probably had hundreds of tenants since its inception in 1954 and it is folly to try to list them all, but as we have information we will present it here. As you can see, information was available from documents in 1964 and 1966.
For the history of the complex, see BELT LINE INDUSTRIAL PARK HISTORY
