Patent ID: 7975860

Claim:
A system comprising: a rack having a vertical wall with a set of holes at each of a plurality of elevations, each set of holes including at least a proximal hole having a lateral slot extending from a base of the proximal hole, the proximal hole being evenly spaced apart from a distal hole having a lateral slot extending from a base of the distal hole; and a longitudinally-extending rail having a set of clips for selectively securing the rail to the vertical wall, wherein the set of clips includes at least a proximal clip forming an inverted hook and selectively receivable in the proximal hole at a selected elevation for supporting a proximal end of the rail and a distal clip forming an inverted hook and selectively receivable in the distal hole at the selected elevation for supporting a distal end of the rail; wherein the proximal clip hangs in the proximal hole to limit downward movement of the proximal end of the rail and the distal clip hangs in the distal hole to limit downward movement of the distal end of the rail; wherein the proximal clip is receivable into the lateral slot extending from the base of the proximal hole to limit upward movement of the proximal end of the rail and the distal clip is receivable into the lateral slot extending from the base of the distal hole to limit upward movement of the distal end of the rail; and wherein at least one of the lateral slot extending from the base of the proximal hole and the lateral slot extending from the base of the distal hole is intermediate the proximal hole and the distal hole.
