The assets of Great Lakes Tool Specialties were purchased in December of 1988 and we began manufacturing and selling the tool line at this location. We communicate with the transmission staff at their headquarters location in near-by Galesburg, Michigan to keep our tool line up to date and resolve questions from the field.
