In 1972 Lowry Supply acquired Tri-Co Tool Sales, a firm specializing in precision cutting tools in Cuyahoga Falls, Ohio. This acquisition gave Lowry Supply a bigger presence in the Akron/Canton and Cleveland markets. As Lowry Supply expanded across the region it also moved its headquarters to a bigger location in Salem to house more inventory.
Throughout the rest of the 70s and 80s Lowry Supply grew and adapted as markets changed and its customers needs changed. In 1992 Lowry Supply acquired Adventure Tool Supply in Meadville, Pennsylvania to further extend its reach in the region.
