3. Figure 2AL shows a detail of the overlapping outside rails of a 4 step section. The figure is to be
used for 42'-60' diameter bins. The chart associated with the figure gives an approximate relation
between the two (2) outside rails. This chart is a guideline only. Overlap distances may vary in order
to keep the stairs level. Use a level to ensure the stairs are level in all directions.
