If you used hole numbers 1 and 5 at the front of the rack, hole numbers 8 and 10 will align to holes on the vertical rail (for whole-U alignment).
If you used hole numbers 2 and 6 at the front of the rack, hole numbers 7 and 9 will align to holes on the vertical rail (for half-U alignment). See Figure 2-3.
