Terminal Supply Company is a Michigan based company providing superior MRO parts and service for 57 years. Our founder, Dave Leslie, had the goal of providing every customer the perfect blend of quality, service and price. What started in the trunk of a 1964 Plymouth has developed into stocking facilities in Detroit (Troy), and Grand Rapids, Michigan, Chicago, Cleveland, Minneapolis, St. Louis, Louisiana and Arizona with over 170 employees. The original product offering of terminals, wire, ties and tape has expanded greatly. Terminal Supply has grown into a full service distributor carrying everything from maintenance supplies to hydraulic fittings. In 1998 Terminal Supply ventured into the wire harness manufacturing arena at the urging of our customer base. In less than 10 years, our manufacturing division has grown from two employees and a workbench into a fully automated 30,000 s.f. facility at our Troy, Michigan headquarters, employing more than 40 people.
