ABSTRACT:
A merchandising display system and the method of making its posts and struts, using pre-decorated strip material having surfaces such as polished metal or wood-grained vinyl that are covered by removable protective strips. A plurality of elongated sections of the strip material are bent longitudinally to form side portions of the desired cross-sectional shape, including overlapping portions defining longitudinal grooves, and are secured together by rivets in the grooves. The overlapping portions are formed with aligned slots and aligned countersunk rivet holes which serve as aligning abutments in the assembly process. The protective strips are slit in the grooves for quick and neat removal. The grooves in the posts have slots for receiving tabs of tightening mechanisms in the ends of the struts, each including a base plate that is movable longitudinally of the strut by a screw mechanism. Different embodiments are shown for the base plates and the guiding of the base plates for sliding on the struts.
