ASSEMBLY INSTRUCTIONS
BEFORE YOU BEGIN
1. Lay out all components and hardware to ensure that you have everything listed on Page 4 & 5.
2. The desk weighs over 100 lbs. Two people are needed to turn or move desktop and some components.
When turning or moving the assembled desk, grab it by SUPPORT BRACKETS (not the desk top).
3. Assemble on soft and non-abrasive surface to avoid scratch or damage to the desk top.
1) UNFOLD FRAME & INSTALL DESK SUPPORT BRACKET
1) Unfold legs (Part #3) until the holes on the legs line up with the Crossbeam (Part #5).
2) Slide in Support Bracket (Part #4) into Crossbeam (Part #5).

3) Insert Bolt Sleeves through holes on the Crossbeam (#5) and Leg (#3).
4) Insert M8x25 Screws (A) into sleeves and tighten with 6mm Allen Wrench (J).
5) Tighten two pre-installed M8x25 Screws with 6mm Allen Wrench (J).

2) ALIGN/EXTEND DESK FRAME & MOUNT DESKTOP
2A) Mounting the ApexDesk Elite 60” Top
1) Place desktop on a flat and non-abrasive surface with screw holes facing up. With two people, carefully place
assembled frame onto the desk top. The frame is heavy. Two people are needed to move it and to turn the desk
over after it is fully assembled.
2) Align left Support Bracket (#4) with pre-installed anchors on the top and secure it half-way with 3 Screws (B). Do
not tighten the screws yet.

Right Support

3) Loosen 8 pre-installed M6x6 Hexagon Screws (D) as shown in the diagram below with 3mm Allen Wrench (H).
This unlocks connecting inner bars in the middle section of the crossbeam and allows the crossbeam to be extended
or retracted to accommodate different top widths.
4) Grab the right lifting column, pull/ push to align the right Support Bracket (#4) with the pre-installed anchors on
the top.
Use 3mm
Allen
Wrench (H)
to unscrew

10
5) Tighten all screws once every part is lined up correctly. If you are unable to tighten Screw (D) or if Screw (D) falls
into the crossbeam, it is because the connecting bars of the crossbeam are out of position. Correct it by sliding the
bar to the left or right and make sure the bars are directly under the screw holes.
6) Optional. Eight Washer Screws (F) are included for tops larger than 72” or for extra security. However, most users
don’t install those screws. For those who do, they rarely use all eight screws. Please note pilot holes are not pre-
drilled on the ApexDesk Elite and Vortex tops. The Washer Screws are self-drilling. Use a power tool to install.
7) Use two ST4.8x13 pan head screws (E) to secure the memory controller to the desktop. Please note pre-drilled
pilot holes are only available on the right side of the desk.
Use ST5x12 Hexagon
Washer Screw (F) to secure
Crossbeam to tabletop
Use M6x16
Hexagon Screw (B)

11
2B) Mounting the ApexDesk Vortex 60” Top
Follow the same basic steps from 2A-1 thru 2A-5. The only difference is that Vortex top requires four screws on
each side.

Optional:
Use 8pcs of ST5x12
Hexagon Washer Screw (F) to
secure Crossbeam

12
2C) Mounting Non-ApexDesk Tabletops
If you are using your own top, we recommend that you use a top between 48” to 78” in width and 28” to 38” in
depth. Top can be installed either with anchor/screw or wood screws. Please make sure the lenth of screw does not
exceed the thickness of your top when wood screws are used. For best stability, the crossbeam should be centered
with support brackets about 2” to 3” from the edge.
Optional:
Use 8pcs of ST5x12
Hexagon Washer Screw (F) to
secure Crossbeam

13
3) INSTALL DESK FEET
Attach each foot to each Desk Leg (#3) with four M6x40 screws (C). Use 5mm Allen Wrench (I) to tighten
screws.

14
4) CONNECTING CABLES
1. Connect memory controller (#7) cable to the left plug on control box (#6).
2. Connect motor cables to control box (#6) by threading them thru the cable guards. Motor cables can be
connected to either port and interchangeably. Switching cables from one port to another may be needed
when troubleshooting. Please refer to trouble-shooting section for details.
3. Plug power cord to control box.
4. Plug power cord to a power outlet.
5. Your desk is now fully assembled. Proceed with initializing (see next section) before turning desk over.
