Until 1937 no one had ever seen an all-glass door, without a frame around the glass-and perhaps no one had ever thought of such a door. However, in that year, Herculite Doors entirely of glass became an accomplished fact. They were conceived in the course of conversation between the president of a large corporation and one of the technical representatives of the Company discussing the expressed desire of the tenant for an all-glass, clear-view entrance to his building. The first installation was made in the entrance foyer for the Bank of the Manhattan Company.

A well-known architectural journal has stated that Herculite Doors constitute one of the real contributions to architecture in modern times. Herculite Doors consist of free standing, solid, all-glass panels of ¾ inch thick Herculite Polished Plate Glass essentially devoid of any surrounding frame or cross sash except that necessary for the accommodation of operating equipment. They constitute an integral part of the display facilities of the establishment by affording uninterrupted view of the interior areas and thereby present a definite invitation to enter.
