Telescope Dual Table Bases with Beam (with or
without Dual Utility Trays) - Standard Electric
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.
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.
