20. Place the base structure in its intended
location. Adjust levelers to ensure
that the Beams and Crossbars are

leveling glides to achieve this, allowing
the triangular crossbar structure to
deviate from horizontal, if necessary.
21. Set the outer columns to be plumb/
parallel to the center columns by
adjusting the position of the rails
within the center column cradles (GG/

as needed. Once plumb/parallel is
achieved, tighten all the screws (M)
in the cradle clamp brackets (D).
