ABSTRACT:
A cross bar is provided for interconnecting two parallel spaced-apart beams of a rack construction, wherein each beam has an inner ledge having a plurality of longitudinally spaced-apart apertures therein. The cross bar is in the form of a rectangular open-bottom channel member with one leg longer than the other, the long leg being integral along the entire lower edge thereof with a laterally outwardly extending flange. Two notches are respectively formed in the flange predetermined short distances from the opposite ends thereof, with the portions of the flange between the notches and the adjacent ends defining tabs dimensioned for insertion into selected ones of the apertures in the beams so that the short leg of the cross bar will rest upon the beam ledges with the top of the cross bar disposed substantially horizontally, the inner edges of the beam ledges being accommodated in the cross bar notches.
