Terminal Supply Company Information

Terminal Supply Company, founded in 1966, is a Michigan-based leader in Electrical MRO supplies for the Heavy-Duty Equipment and Truck & Trailer industries. What began in the trunk of a 1964 Plymouth has grown into a company with over 250 employees, stocking facilities in Troy (Detroit), Chicago, Cleveland, Minneapolis, St. Louis, and Louisiana, and a fleet of 40+ locally stocked vans. In the late 1990s, we launched TSC Manufacturing to deliver top-tier custom cable assemblies and wire harnesses. From small batches of pigtails and jumpers, the division has expanded to two dedicated facilities in Troy, Michigan (2008 and 2021). In 2023, Terminal Supply expanded into Mexico, boosting both capacity and workforce to enhance our competitive edge.
