ABSTRACT:
A panel device, particularly a sign board is made up of at least one channel-section display member having a plain front face of predetermined width force fitted onto a support member, which is an extrusion-formed item, by interaction between the legs of its channel and projections on the support. The projections on the support are arranged in pairs and the pairs are regularly spaced apart along the support. The spacing between pairs is the same as increments in width as between different display members so that display members of the same or different widths may be fitted to the support member. The plain face of the display member is to bear indicia or the like.
