4. Determine requirement for Starter
Crossbars (G) and/or Mid Crossbars (H),
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 required crossbar (G/H), place
a Pull Block (I) into each end, and attach
securely with (2) 5/16-18 x 3/4" flat head
hex machine screws (N) per pull block in
the underside of the crossbar.

Steps 9 & 10
CONNECT BEAM TO CROSSBARS
6. Ensure the crossbars are oriented right
side up and so the insides are facing one
another. Attach a Center Beam Mounting
Plate (U) to the inside of each crossbar,
using (4) 1/4-20 x 3/4" button head
machine screws (V) per plate. Insert M8-1
1/4 x 8mm hex set screws (W) into both
tabs on the sides of both plates (U), such
that the hex recesses are outward.
7. Ensure the Center Beam is 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 the beam to one of the mounting
plates (U), and secure by tightening the set
screws (W) with a 4mm hex driver. Repeat
for the other end.
8. Turn the large beam/crossbar "I" assembly
upside down. Position the (4) legs upside
down as well, and in their relative positions
at the ends of the crossbars.

CONNECT CROSSBARS TO LEGS
9. With the legs upside down, connect the
leg assemblies to the crossbars by sliding
the ends of the crossbars onto the welded
column brackets, and joining with (2) 5/16-
18 x 3/4" 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.
10. Place a washer (P) on a 5/16-18 x 2"
button head hex machine screw (O) and
insert it into the bottom of the crossbar at
an angle to penetrate the pull block and
thread into the column bracket. Torque
screw to 150 in. lbs. (17 Nm). Repeat for
the three other crossbar ends. Tighten
the (4) pairs of flat head machine screws
previously left loose. Turn assembly right
side up.
