ABSTRACT:
A rack which comprises a pair of parallel side beams in which each defines a groove facing the other side beam. The rack may be made by inserting between the beams at least one crossbar with the opposed ends of the crossbar each occupying a facing groove of the side beams, and with the crossbar extending between the beams. One may flex the beams outwardly as necessary to insert the crossbars. One then inserts between the beams a spacer bar, positioning the spacer bar centrally along the beam, with the opposed ends of the spacer bar each occupying a facing groove of the beam, and with the bar extending between the beams. The spacer bar is shorter than the crossbar. Thus, upon tightly securing each side beam to an end of the spacer bar, one draws a central portion of each beam inwardly relative to the crossbar or crossbars, to provide high constricting pressure securance between the ends of the crossbar and the side beams, while the spacer bar is under tension.
