Abstract

See full text

Main runner members and cross members having an inverted T-shaped configuration characterized by an outer edge of the flanges being bent upwardly at an angle to form a bevelled edge to give the flanges an appearance of being substantially thicker than the material used to form the flange. The cross members include a connecting element, preferably formed as a separate element, having spacer bumps, and a U-shaped tab extending from one surface, the U-shaped tab forming a first abutment and a portion of the element is cut and deformed out of the plane of the element on an opposite surface to form a second abutment surface to coact with the first abutment surface of an adjacent connecting element to hold the two aligned cross members in a slot of a main runner.
