A wire flow rack system including a longitudinal wire, a roller wire, a roller and an optional cap. The roller wire is joined with and transverse to the longitudinal wire and includes an unsupported free end that projects beyond the longitudinal wire. The roller defines an axial bore, and is positioned on the free end so that the it is free to rotate about the roller wire. A end element, for example, a cap, can be joined with the free end to prevent the roller from disengaging the free end. The cap can be friction fit with the free end and easily, manually replaceable relative to the free end, without the use of tools.

1. A wire flow rack system for handling articles comprising:at least two substantially parallel longitudinal wires separated from one another by a first distance and lying in a first plane over which the articles flow;at least two substantially parallel transverse wires joined with and transverse to the at least two longitudinal wires, each of the transverse wires of a first length that is greater than the first distance so that the transverse wires extend beyond the at least two longitudinal wires, at least one of the transverse wires bent upward relative to the first plane beyond at least one of the at least two longitudinal wires to form an upwardly extending transverse wire portion;a bumper wire joined with the upwardly extending transverse wire portion, the bumper wire extending substantially parallel to the longitudinal wires, whereby the bumper wire forms a boundary for guiding the articles over the first plane;a roller wire joined with and transverse to the at least two longitudinal wires, the roller wire positioned between the at least two transverse wires, the roller wire extending beyond at least one of the two longitudinal wires to form a first free end of a second length;a one-piece plastic roller of a generally cylindrical shape, having a width, and defining an axial bore, the roller rotatably mounted to the first free end by positioning the axial bore over the first free end of the roller wire, the second length being greater than the roller width so that a first free end portion extends beyond the roller, whereby the roller provides a rolling surface over which the articles flow; anda cap including a flange, the cap substantially only frictionally engaging the first free end portion, whereby the cap is manually removable from the first free end portion, wherein the flange is adapted prevent the roller from disengaging the first free end of the roller wire.2. The wire flow rack system of claim 1 wherein the roller is constructed from substantially only at least one of polyurethane, polyethylene, and polypropylene.3. The wire flow rack system of claim 1 wherein the roller wire is of third length that is greater than the first distance so that the roller wire extends beyond both of the at least two longitudinal wires to form a second free end opposite the first free end, the second free end of a fourth length, wherein another roller is rotatably mounted to the second free end.4. The wire flow rack system of claim 3 wherein including a plurality of roller wires, wherein the roller wires and transverse wires are in alternating sequence.5. The wire flow rack system of claim 1 wherein the cap includes a first portion sized to frictionally fit over the first free end.6. The wire flow rack system of claim 5 wherein the cap includes a flange extending radially outward around at least part of the first portion.7. A wire rack system for handling articles comprising:a longitudinal wire;a roller wire transverse to and fixedly joined with the longitudinal wire, the roller wire extending beyond the longitudinal wire to form a first free end of a first length;a bumper wire coupled to and aligned with the longitudinal wire, the bumper wire forming a boundary that guides the articles generally over the longitudinal wire;a roller of a generally cylindrical shape, having a width, and defining an axial bore, the axial bore positioned over the first free end of the roller wire so that the roller is free to rotate on the free end, wherein the roller wire first length is at least about half as great as the roller width, wherein the roller provides a rolling surface over which the articles flow; andmeans for preventing the roller from disengaging the first free end of the roller wire, the preventing means manually removable from the first free end.8. The wire rack system of claim 7 wherein the roller wire includes a second end extending beyond the first free end on an opposite side of the longitudinal wire, the roller wire bent upward near the second end.9. The wire rack system of claim 8 wherein the bumper wire is joined with the roller wire at the second end of the roller wire.10. The wire rack system of claim 9 comprising a plurality of transverse wires, each transverse to the longitudinal wire, wherein the roller wire is disposed between at least two transverse wires.11. The wire rack system of claim 7 wherein the preventing means is a cap including a flange, the cap secured to the first free end substantially only via a friction fit with the first free end.12. The wire rack system of claim 7 wherein the roller is a one-piece construction formed from at least one of polyurethane, polyethylene, and polypropylene.13. The wire rack system of claim 7 wherein the longitudinal wire, the roller wire and the bumper wire are formed from solid, cylindrical rods of metal.14. A wire rack comprising:a longitudinal wire;a transverse wire joined with and transverse to the longitudinal wire;a roller wire joined with and transverse to the longitudinal wire, the roller wire adjacent the transverse wire, the roller wire including an unsupported free end that projects beyond the longitudinal wire;a roller defining an axial bore, the roller positioned on the free end so that the free end is at least partially inserted in the axial bore; andan end element replaceably joined with the free end to prevent the roller from disengaging the first free end of the roller wire, wherein the roller is free to rotate about the free end between the longitudinal wire and the end element.15. The wire rack system of claim 14 wherein the end element is secured to the free end substantially only via a friction fit with the free end.16. The wire rack system of claim 14 wherein the end element is a cap including a first portion defining an aperture and a flange.17. The wire rack system of claim 14 wherein the roller wire free end defines a hole, wherein the end element is a fastener threaded into the hole, the fastener including a head of a size greater than the axial bore.18. The wire rack system of claim 14 comprising a bumper wire joined with at least one of the transverse wire and the roller wire, the at least one of the transverse wire and the roller wire being substantially parallel to the longitudinal wire.19. The wire rack system of claim 14 comprising a bearing within the axial bore, the bearing engaging the free end so that the roller rolls.20. The wire rack system of claim 19 wherein the transverse wire is upwardly bent to form an upwardly projecting portion and the bumper wire is joined with the upwardly projecting portion.
