Abstract

A self-supporting modular switchboard panel formed from a plurality of rectangular frame elements with four solid side faces. The corner edges are beveled to provide a 45.degree. angle with the side faces so that when four frame elements are placed together to form a rectangular section, the center thereof forms a square which serves as a perch for retention clips and cover fasteners. Projections and grooves are disposed on opposed side faces for various retention possibilities.
