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 has at least one collar formed thereon; a lower beam portion extends along the same end of the carton and has detents formed thereon for engaging at least one cutout to removably attach the bracket to the carton; and plural column portions rigidly attach 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 detents have engaged the cutout. The bracket is easily installed upon the carton by engaging the collar with a stacking alignment tab of the produce carton and snapping the detents of the lower beam portion into the cutout.
