Fletcher's Wood Risers.
The device here illustrated was designed especially for running bare and insulated wires or copper rods in electric light stations and power plants, but there is also other nice interior wiring for which it will be found very convenient. It is placed upon the market by The Electrical Supply Company of Chicago.
It complies fully with underwriters' rules, and is a handsome and efficient insulator. The base is smoothly finished maple. In the sizes with 1/8 and 1/2 inch opening the insulator is porcelain. For larger sizes, opalescent glass is used.
The Electrical Supply Company of Chicago is prepared to furnish them in any quantity.
