Assembly Instructions
Assembling the Base
NOTE: Lay out all components and hardware on a clean surface to ensure you have all components and
hardware listed on the parts page.
1. Fully separate the Crossbar Ends (P4). You
will find the Crossbar Center Rails (P5) inside.
2. Position one of the Crossbar Ends (P4) on its side.
Place one of the Legs (P1) into the Crossbar End (P4) ensuring the
bar (arrow) is on top in relation to the Leg (P1). Line up the holes
on each Leg (P1) with the holes on each Crossbar End (P4).
3. Using the supplied Allen Wrench, insert four M6*14
Machine Screws (P14) through the holes in each Crossbar
End (P4) going into the Leg (P1) and rotate each screw just
a few turns. You will need to flip the Crossbar over to gain
access to all four screws. Repeat Step 3 with the other two
Crossbars.
WARNING: DO NOT tighten the screws at this point.
NOTE: If you drop a screw inside the Crossbar End (P4), simply tilt to
retrieve.
4. Prop up one of the Crossbars from Step 3, as shown. Insert four
M6*14 Machine Screws (P14) through the four holes of the side
bracket (P6 or P7) going into the Crossbar End/Leg assembly.
Using the Allen Wrench, rotate each screw just a few turns.
Repeat Step 4 with the other two Crossbars.
WARNING: If you are having difficulty inserting any of the screws from
Step 3 or 4, it is because some of the screws are too tight.
5. Tighten all the screws from Step 3 and Step 4.

6. Remove backing from the Noise Attenuation Pads (P13) and
position along the brackets as shown.
7. Slide the two Crossbar Center Rails (P5) into the two Crossbar Ends (P4) ensuring:
a. The Crossbar with the short Side Bracket (450)(P7) is placed on the side that will be the center
leg of the desk base.
b. The slots in the Center Rails (P5) face inward.
c. The slots in the Center Rails (P5) are closer to the top edge when the assembly is upside down
(see inset).
8. For the two Crossbars that will be the outer legs of the desk
base, attach a Foot (P2) with four M6*14 Machine Screws (P14)
and tighten the screws in a cross pattern.
9. For the one Crossbar that will be the center leg of the desk
base, attach the Stand-Off (P3) with four M6*14 Machine
Screws (P14) and tighten screws in a cross pattern.
Attaching The Desktop
Note: Your desktop is pre-drilled. Check both sides of the desktop before placing the desk base on the
underside of the desktop.
1. Place desktop face down on a clean surface.
2. Carefully place the upside down 2-leg desk base on the
underside of the desktop on the longer side and/or the
side with a seam in desktop as shown. Adjust the width of
the 2-leg desk base to fit the pre-drilled desktop by sliding
the two halves outward. Place the 1-leg desk base on the
shorter end of the pre-drilled desktop.
3. Double check that the desk base in properly aligned with
the pre-drilled holes on the underside of the desktop.

WARNING: Use caution that the screws are not overtightened so they do not puncture the top surface when
screwed all the way in.
a. Attach the 2-leg desk base to the underside
of the desktop using eight M5*20 Wood
Screws (P16).
i. 3 per Side Bracket (P6) –6 total
ii. 1 per Crossbar End (P4) –2 total
b. Attach the 1-leg desk base to the underside
of the desktop using four M5*20 Wood
Screws (P16).
i. 3 per Side Bracket (P6) –3 total
ii. 1 per Crossbar End (P4) –1 total
NOTE: It is recommended that you pre-drill any holes needed for fasteners connecting the Control Box (P8)
and Switch (P9) to the desktop. Never use countersunk screws.
4. Attach the Control Box (P8) to the underside of the destop using two M5*16 Wood Screws (P17).
Ensure enough clearance to the wire ports for the cable connections.
5. Place the Switch (P9) so the front of the Switch is flush with the front desktop edge. The Switch may
be placed anywhere along the front edge of the desktop but the recommended placing is toward the
end so it does not interfere with your chair when seated. Use two M5*16 Wood Screws (P17) to
attach the Switch to the desktop.
WARNING: Use caution that the screws are not overtightened. Overtightening could cause damage to the
wood desktop or other components.
6. Connect the LC Cables (P11 & P12), Switch Cable (P9), and the
Power Cord (P10) to the Control Box (P8) as per the diagram.
The adhesive-backed Cable Clips (P18) can be used to secure
the Cables and Switch Cable so they do not hang.
7. With at least two people hold the Desk Base (NOT THE DESKTOP) and turn the desk right side up.
Adjust the pre-installed Leveling Studs on the Feet (P2) and the Stand-Off (P3) as needed to level the
desk.
