Abstract
Abstract Covers for terminal boxes generally rectangular in shape used in telephone installation equipment, said covers being made of transparent plastic material, each comprising a flat top for contacting and covering the open face of a terminal box, integral side walls provided with inwardly projecting means for engaging outwardly extending side wall members on said terminal box, and means preventing longitudinal sliding movement of the cover relatively to the terminal box. Said sliding movement preventing means may be and extensions at opposite ends of the cover top at right angles thereto partially closing said box ends and also serving to prevent foreign matter from falling into the box, or may be a rib on the inner surface of the top extending onto the inner surface of the cover side wall for entering spaces between the side wall members of the terminal box. The cover occupies limited space sidewise of the terminal box and thus permits the covered boxes to be mounted adjacent each other on a wall or support with little space between them for manipulation of the covers.
