Original electrical trade vintage catalog for MONOWATT INCORPORATED, was located in Providence, RI. Manufacturers of electrical wiring devices, including wall plate, box, combination unit, double outlets, all-in-one surface units for basements, attics, garages, barns, cabins, roadside stands and warehouses. For residential, commercial and industrial use. Disbound from a large 1949 electrical construction materials book, this unique old four page technical specifications brochure would display wonderfully matted and framed. A marvelous addition to your retro electric equipment library. Pages are detached and contains a small amount of residual glue on edge.
