A modular conveyor apparatus includes a plurality of substantially identical conveyor segments. Each conveyor segment has a pair of laterally spaced protrusions or hooks extending from one end thereof. Each conveyor segment has a plurality of spaced openings or slots along at least one of its side walls, so that two like conveyor segments can be connected together perpendicularly with the hooks of a first segment received in the side wall slots of a second segment. Thus the perpendicular connection between two conveyor segments may be made at any selected one of a plurality of locations along the length of each conveyor. Provision may also be made for end to end connection of the conveyor segments.
