William Wallace Grainger founded the company in Chicago in 1927 selling electric motors by catalog, and the thick Grainger catalog became a fixture in maintenance departments. It distributes maintenance, repair, and operating supplies to businesses and institutions, competing on breadth and next-day availability rather than price. A separate endless-assortment segment operates Zoro and Japan's MonotaRO on a pure ecommerce model. Amazon Business is the structural competitive threat. Headquarters are in Lake Forest, Illinois.
