ABSTRACT:
A casing system for laying electric supply conductors and, if desired, signal conductors along the outer surfaces of walls comprises pre-fabricated, unitary, permanently closed casing sections of a variety of fixed lengths with built-in conductors. Each casing section is provided with a number of built-in access modules permitting the mounting of installation components, such as wall sockets, and the establishment of electrical connection between these and the built-in conductors without interfering with the integrity of the casing sections. The system further comprises sliding cover sections for covering the gaps between adjacent casing sections and between casing sections and corner and end sections also belonging to the system. Standard lengths of casing sections, corner sections, and sections, and sliding cover sections are so selected thay any length of wall can be covered by the system without cutting or otherwise interfering with the casing sections as manufactured.
