Original 1943 electrical trade vintage ad for OKONITE COMPANY.  (Hazard Insulated Wire Works Division). Main office and plant was located in Wilkes-Barre, PA.

Manufacturers of Rubberless Building Wire.

To assist in conserving rubber, Hazapak Rubberless Wire saves rubber, saves tin and saves critical synthetics.

Hazapak Rubberless Building Wire is approved by the Underwriters Laboratories, Inc., under the provisions of Interim Amendments 44 and 69 of the National Electrical Code. 

In this new rubberless building wire, in place of the familiar rubber insulation, there are two separate materials - (1) a thin layer of Kodapak (cellulose acetate butyrate) - a pure insulating material, covering the copper conductor, over which is wrapped - (2) a compacted cushion of crumpled moisture-proofed kraft paper for mechanical protection.

Unbound from a 1943 electrical engineering magazine, this unique old one-page advertisement would display beautifully matted and framed. Nice graphics. World War 2 propaganda. A fabulous addition to your retro electrical library.
