The Ketler-Elliott Erection Co. was a Chicago-based firm known for heavy construction, particularly metal structures like bridges. The company also founded the Pensacola Shipbuilding Company for WWI/WWII ship production. While most of the work done by this company is outside the scope of this site, in the early 1900's the company did produce the Ketoco Tools line of hand forged tools. These tools include items used in metalworking and boiler making.
