Abstract: A shelving/display and merchandising system for stores includes, a pair of elongate channel-section runner elements intended to be mounted in a vertically spaced horizontal arrangement. Vertical post members are fitted to the runner elements and provide support for brackets. Each runner-element has its upper and lower side flanges formed with a row of slots and the post members have tongues to co-act with these slots. One tongue is shorter than the other to enable mounting and dismounting of the post members on the runner elements with the latter fixed in place.
