Abstract: Brackets are provided that may be economically formed of only several pieces, and which pieces may be easily and mechanically assembled onto side framing of the conveyor system. Each bracket has a horizontal disposed piece and a vertically disposed piece which are arranged to lie adjacent and cross corresponding vertical and horizontal sides of the side framing, generally meeting across the lower corner and extending beyond the corresponding sides. Clamps cooperate with the brackets to form elongated slots, operable to allow the secure attachment of attachments or accessories usable with the conveyor system.
