An undriven gravity roller conveyor is disclosed in which a plurality of discrete, elongate channel members are attached in a spaced apart, parallel relation to a base structure. The separation between neighboring channel members is made equal to the separation between the opposite side walls of each channel member, thereby providing a plurality of rows extending between the side walls of the channel members. Open slots equidistantly spaced apart are formed along the upper edges of each side wall. The slots are aligned in parallel columns substantially perpendicular to the length of the rows. Load-bearing rollers mounted upon axles are arranged in rows both between the opposite side walls in each channel member and between adjacent side walls of neighboring pairs of channel members, with the axles of the rollers held within the slots. The spacing between slots is substantially less than one-half of the exterior diameter of the rollers.
