4. Determine requirement for Starter
Crossbars (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.
5. For each outer crossbar (G/H), place a
Pull Block (I) into each end, and attach
securely with (2) / -18 x ¾" flat head

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)

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.

crossbar ends. Tighten the (6) pairs of flat
head machine screws previously left loose.
Turn each assembly right side up to
perform the next step.
9. Ensure the Center Beams are oriented
correctly (the top of the beam has a slot
within a deep recess, the bottom of the
beam has a slot within a wide recess).
Mate a beam to the previously attached
mounting plate (U), and secure by
tightening the set screws (W) with a 4mm
hex driver.
Repeat for the other two outer leg sets.
