ABSTRACT:
This invention involves connectors for vertical end rectangular grids having spaced pairs of vertical end rails joined to horizontal rods extending between the end rails with vertical spaced rails between the end rails. Each connector includes a rigid, flat plate formed with two or more horizontally spaced symmetrical notches. Each notch has a passage extending inwardly from an end edge of the plate. The passage terminates at two inner opposed concave lobes each of of which slidably engages a respective vertical end rail. The passages permit the plate to move beyond the horizontal rods when the plate is moved along the end rails. A third inner lobe between the two opposing lobes allows the plate to pass free projecting ends of plates can have two, three, four or more notches to hold vertical grids in free standing, upright angular arrays. Stop blocks can be placed below the connectors to hold them in desired positions on the rails supported by the horizontal rods projecting through the rails.
