ASSEMBLY
1. Lay out all components and hardware to ensure that you have all the components and hardware listed on the parts page. Slide the Control Box
(part 6) off the Frame End-CB (part 3a) and set aside. Fully separate Frame End (part 3b) from Frame End-CB (part 3a). You will find the Center
Rails (part 4) inside.
2. Place one of the Legs (part 1) into the Frame End-CB (part 3a) ensuring the bar (arrow) is
on “top” in relation to the Leg (part 1).
Line up the holes on the Leg (part 1) with the holes on the Frame End-CB (part 3a).
Using the supplied Allen Wrench, insert (4) M6x10 Machine Screws (part 10) through the
holes in the Frame End-CB (part 3a), going into the Leg (part 1) and rotate each screw just a
few turns. Aer all four (4) M6x10 Machine Screws (part 10) are inserted, tighten all four (4)
screws.
Do the same for the other Leg (part 1) and the Frame End (part 3b).
3. The Frame End-CB (part 3a) should be placed on the side of the desk where you plan to
mount the Control Box (part 6) and the Handset (part 7).
Slide the Side Bracket (part 5) into the Frame End-CB (part 3a). Insert two (2) M6x14
Machine Screws (part 11) through two (2) holes in the boom of the Frame End (part 3a)
going into the inserted Side Bracket (part 5). Using the supplied Allen Wrench, rotate each
screw just a few turns. Aer both M6x14 Machine Screws are inserted, tighten both screws.
Do the same for the other frame end/leg assembly.
4. Slide the two (2) Center Rails (part 4) into the two Frame Ends (part
3a & 3b) ensuring:
a. The slots in the Center Rails (part 4) face inward.

ASSEMBLY
6. Your desktop may or may not be pre-drilled. Check both sides of the desktop before
placing the desk base on the underside of the desktop.
Adjust the width of the desk base to fit the desktop by sliding the two halves outward.
We recommend leaving at least 1/2” of the desktop width (on each end) protruding
beyond the frame width and centering the Side Brackets (part 5) fore and a.
5. For each leg assembly, aach a Foot (part 2) with four (4) M6x14 Machine Screws (part 11)

7. If the desktop is pre-drilled, perform Step 8 before Step 7.
If the desktop is not pre-drilled, lock the position of the Center Rails (part 4) using
eight (8) M6x10 Machine Screws (part 10).
Ensure that the M6x10 Machine Screws (part 10) contacts the Center
Rails (part 4) by sliding the Center Rails (part 4) as needed.
8. Double check that the desk base is properly positioned on the underside of the
desktop.
Aached the desk base to the underside of the desktop using seven (7) M5x20 Wood
Screws (part 12).
Aach the Handset (part 7) so the front of the handset is flush with the front desktop
edge (or recessed up to 1/8”). The Handset may be placed anywhere along the front
edge of the desktop but we recommend placing it toward an end so it does not
interfere with your chair when seated. Use two (2) M5x16 Wood Screws (part 13) to
aach the handset to the desktop.
Double-check that the wood screws are not too long for your desktop
and won’t puncture the surface when screwed all the way in.
We recommend that you pre-drill any holes needed for fasteners if
your desktop is not pre-drilled. Never use countersunk screws.
Ensure that the M6x10 Machine Screws (part 10) contacts the Center
Rails (part 4) by sliding the Center Rails (part 4) as needed.
