These tiles were used to carry wires and utilities underground. Many of these tiles would be connected in a row, then buried. They protected and separated the wires.
This is a salesman version of the telephone tile. The salesman would carry this to the client interested in the product in stead of transporting the full size tiles which could weigh more than 100lb.
This item is significantly less common than the full size conduits. Full size conduits were made and sold to individuals all over the country, They can be found in yards and other areas. There were very few salesman tiles made because they were only used by the salesmen. They were not sold to individuals, they were not used in the same manner as the full size ones. Salesman conduits will not be found in yards, because they were never used there.
