Abstract
The visitor station permits good visual and voice communication between persons, such as a visitor and an inmate, disposed on opposite sides of a wall within a jail, prison or similar institution, but prohibits physical contact and the passage of drugs and other materials between such persons. The modular and adjustable construction of the station permits its expeditious and economical installation, from prefabricated components and in either one-unit or multiple-unit arrays, in institutions having different size requirements. Each unit of the station includes, in addition to other components, a hollow box-like member which transmits sound both through its hollow interior and through its structure between persons using the unit, and which also provides shelf-like areas usable for writing and similar purposes by such persons.
