Abstract
In an array of parallel cross bars, each cross bar has a crenellated edge with alternating recesses and projections. A first locking opening extends through the length of the each cross bar, at least partly within the projections. A number of bearing bars each include second locking openings spaced along the length of the bearing bar. The bearing bars are assembled with the cross bars with the bearing bars nested in the recesses in the cross bars. The first and second locking openings are in alignment. A locking member is received in the aligned locking openings to interlock the bearing bars and cross bars in a rigid, strong, durable and attractive grille structure.
