Con-Cor - 0004-003028 - Tractor-Trailer, Modern - Safety-Kleen - 2-Pack

Prototype History: A semi-trailer truck (more commonly semi truck or simply "semi") is the combination of a tractor unit and one or more semi-trailers to carry freight. A semi-trailer attaches to the tractor with a fifth-wheel coupling (hitch), with much of its weight borne by the tractor. The result is that both the tractor and semi-trailer will have a distinctly different design than a rigid truck and trailer.

Road Name History: Safety-Kleen Systems, Inc. is a company that provides services such as collecting and recycling oil, providing industrial cleaning, and handling industrial waste. In addition, their products include cleaning equipment, antifreeze and coolant, windshield cleaner, and re-refined oil products.

Brand/Importer Information: Con-Cor has been in business since 1962. Many things have changed over time as originally they were a complete manufacturing operation in the USA and at one time had upwards of 45 employees. They not only designed the models,but they also built their own molds, did injection molding, painting, printing and packaging on their models.

Currently, most of their manufacturing has been moved overseas and now they import 90% of their products as totally finished goods, or in finished components. They only do some incidental manufacturing today within the USA.

Important Note: The Con-Cor product numbering can be very confusing. Please see here in the article how to properly enter Con-Cor stock numbers in the TroveStar database.
