(G) and/or Mid Crossbars (H) for the three pairs
of outer legs, based on table application.
NOTE:
The Starter Crossbars will have holes
on the inside of them to accept the legs and
beam (and utility trays, where specified). Mid
Crossbars will have holes on both sides; i.e.,
the inside has holes for the legs and beam
(and utility trays where specified), and the
outside has holes for linking brackets.

6. Ensure the three crossbars are oriented right
side up and so the insides are facing one
another (towards the center of the triad).
Attach a Center Beam Mounting Plate (U) to
the inside of each crossbar, using (4) ¼-20 x
¾" button head machine screws (V) per plate.
Insert M8-1.25 x 8mm hex set screws (W)
into both tabs on the sides of all three plates
(U), such that the hex recesses are outward.

7. For each outer leg set, turn a crossbar
assembly and the corresponding (2) leg
assemblies upside down, and connect the
leg assemblies to the crossbars by sliding
the ends of the crossbars onto the welded
column brackets. Join with (2)
flat head hex machine screws (N), loosely,
into each bracket. Do not tighten at this
time. Allow the screws to seat in the counter
sinks and perform the next steps.
