ABSTRACT:
A bracket for strengthening a produce carton and the resultant carton such as those commonly used to transport and store grapes has an upper beam portion extending along one end of the carton and configured to hook over that end of the carton; a lower beam portion extending along the same end of the carton and having detent means formed thereon for engaging at least one of the cutouts to removeably attach the bracket to the carton; and plural column portions rigidly attaching the upper beam portion to the lower beam portion. The lower beam portion has at least one stop formed thereon to prevent upward movement of the bracket after the detent means has engaged a cutout. The bracket is easily installed upon the carton by hooking the upper beam portion over the end of the carton and snapping the detent means of the lower beam portion into the cutouts.
