Two-post Flush-mount Configuration
1 For this configuration, the castings must be removed from the front side of
each ReadyRail assembly. See Figure 1-20, item 1 on page 44. Use a Torx
driver to remove the two screws from each front flange ear (on the switch
side of the rail) and remove each casting. Retain the castings for future
rack requirements. It is not necessary to remove the rear flange castings.
