Abstract

A wall system for partitioning floor space includes a framework comprising top and bottom horizontal rails interconnected by a plurality of vertical struts. The wall system further includes the use of diagonal support bars for open frame structures and the use of side and septum display panels for closed frame structures. Additionally, various types of snap-on covers are provided for removably covering the vertical struts. Also, anchoring devices including hook and loop type fastener sheets and adhesive are used to secure the bottom rail against lateral shifting.
