Abstract
In a storage rack comprising two front columns, two back columns, and, at each tier, two side beams, a front beam, and a back beam, a front portion of each side beam projects frontwardly and a back portion thereof projects backwardly. The front portion has a fin projecting upwardly, a notch opening frontwardly below a front part of the fin, and a tab projecting backwardly from the fin. The front beam has a front wall, a back wall, and a lower lip projecting from a lower part of the front wall. Each slot receives the tab of a respective one of the side beams and the lower lip projects backwardly into the front notches of the side beams so as to secure the front beam to the side beams. The back beam is secured similarly to the back portions of the side beams.
