An apparatus and method that effects selectable width of a roller track conveyance system having multiple roller tracks with asymmetric wall heights. The system includes a clip that connects lower or mating walls of two single roller tracks together. The connected roller tracks each have their own set of rollers, which form respective dispensing surfaces. A removable divider bar, which is capable of being selectively placed into the clips between the connected roller tracks, may be placed to divide the dispensing surfaces into separate surfaces or may be selectively removed to form a larger, single dispensing surface.

A system as defined in claim 9, wherein the joining clip has a top portion defining a slot formed therein; and further comprising: a divider bar configured to engage with the slot. 11. A system as defined in claim 10, wherein the divider bar is selectively placed in the slots of the joining clips to divide the first and second roller trays into two dispensing roller trays. 12. A system as defined in claim 9, wherein the tines comprise a center post and a pair of flexible arms, each of the arms being joined at one end to the center post. 13. A system as defined in claim 12, wherein the flexible arms are configured to move toward the center post when being inserted into the respective apertures and move away from the center post when the tines are fully inserted into the aperture such that the tines are locked into the apertures. 14. A system as defined in claim 9, wherein the apertures further comprise guide apertures and the joining clip comprises first and second sides having guideposts configured for insertion into respective ones of the guide apertures to locate the joining clip in a prescribed position. 15. A system as defined in claim 14, wherein the prescribed position comprises a position where the tines may properly engage with the respective ones of the apertures. 16. A system as defined in claim 14, wherein the guideposts have a length greater than a length of the tines. 17. A system as defined in claim 12, wherein the flexible arms and center post define a generally arrow shape profile. 18. A gravity feed roller system for dispensing products comprising: a plurality of rollers; a plurality of roller trays each having first and second substantially vertical sides supporting the rollers to form a first roller dispensing surface, the first vertical side having a first height and the second side having a second height that is less than the first height; connecting means for releasably connecting at least two of the roller trays along the second sides to form a second roller dispensing surface, the second roller surface including at least two of the first roller dispensing surfaces; divider wherein the connecting means includes releasably securing means for releasably securing the divider for dividing the second roller surface into the two first roller dispensing surfaces, wherein the divider is releasably secured in the releasably securing means and said divider is located at a junction of the second sides of the connected roller trays to selectively divide the second roller dispensing surface into two separate product dispensing surfaces. 19. A system as defined in claim 18, wherein the first vertical side extends above the first roller dispensing surface in the vertical direction and the second vertical side lies below the first roller dispensing surface in the vertical direction. 20. A system as defined in claim 18, wherein the means for connecting comprises generally vertically-oriented slots receivably retaining a removable divider bar member to selectively separate the respective first roller dispensing surfaces of the plurality of roller trays. 21. A system comprising: a first roller tray; a second roller tray; a clip selectively connecting the first and second roller trays to form a first roller surface having a first width; and a divider independent of the first roller tray and the second roller tray and selectively engageable with the clip to selectively divide the first roller surface into a second roller surface and third roller surface. 22.
