Step 1 - Inventory of Parts
A. For ease and safety, we recommend using two people for assembly. Before assembly, consider where
you want your desk to be located. Since your new desk is height adjustable, you will want it located
a safe distance from anything that could obstruct the desk from being raised or lowered (like a wall
mounted shelf or cabinet). With an Advanced Keypad, you can set the upper and lower height limits for
your desk to avoid any potential collisions.
B. To avoid any damage to your oor or desktop, we
recommend assembling your desk on a debris-free
carpet or blanket.
C. Ensure you have received all components and
hardware before disposing of any packing material.
Lay out the components from all boxes and make
sure the items and quantities match what is shown
in each of the package contents sections in these
instructions.
D. Inspect the top surface of your desktop for damage
before beginning your frame assembly. This will
save you time if the desktop was damaged in
shipment.
E. The included Allen Wrench Handle (H15) provides increased leverage and a better
grip when tightening the frame screws. Insert the 4mm Allen Wrench (H6) into the
side marked with the number “4”. Push the Allen Wrench all the way into the slot of the
handle until it “snaps” securely into place.

Step 3 - Side Bracket Attachment
A. Slide the tabs of the Side Bracket (P2) into the
Crossbar End (P5) and insert two M6x10 Machine
Screws (H1) through the top of the Crossbar End
as shown. Loosely start each screw by hand.
Once both screws are started, tighten them both
completely.
B. Repeat this step for the 2nd Leg assembly.
• If your Side Brackets came with the Logo Plates
(P16) pre-attached, continue on to Step 4.
P5
H1
P2
• If your Side Brackets came with the Logo Plates (P16) detached and four extra M6x10 Machine Screws
(H1) were in the Side Bracket box, follow Steps C through E below.
C. Insert two M6x10 Machine Screws (H1) through the two larger holes in the face of the Side Bracket (P2)
and into the Leg. Once both screws are started, tighten them both completely.
D. Attach the Logo Plate (P16) by pressing the posts on the Logo Plate rmly into the two smaller holes
in the side of the Side Bracket. The Logo Plate conceals the two screws in the face of the Side Bracket.
When assembling the Legs in the orientation shown, the Logo Plate will need to be attached upside-down
so that it is right-side-up when the desk is ipped over.
E. Repeat this step for the second Leg assembly.
Step 2 - Crossbar End Attachment
A. Place one of the Crossbar Ends (P5) upside down
as shown.
B. Position one of the Legs (P4) so that the back
of the Leg and the back of the Crossbar End are
aligned and ush.
C. Using the 4mm Allen Wrench (H6), loosely in-
sert four M6x10 Machine Screws (H1) through the
Crossbar End holes and into the Leg as shown, but
do not tighten them.
D. Once all four screws have been started, tighten
them using the Allen Wrench (H6).
E. Repeat this step for the second Leg assembly.

B. Place the leg assembly so that the Side Bracket is centered between the front and back edges of the
desktop and approximately 1/2” in from the side edge of the desktop.
C. Make a pencil mark in the center of each of the Side Bracket holes and the
Crossbar End hole. Then move the leg assembly out of the way and drill
pilot holes using a 1/8” drill bit. IMPORTANT: DRILL NO DEEPER THAN
1/2”. To ensure this, we recommend wrapping a piece of tape around
your drill bit 1/2” from the tip. Stop drilling just before the tape touches
the desktop.

A. If you have “tube shape” Crossbar Rails (P6),
position them so that the center indicator marks
are facing up and side slots face inward as shown
here. Slide the Crossbar Rails into the Crossbar
End (P5) of the Leg assembly shown with the
center indicator marks facing up. This will be
the right side Leg of your desk when it is ipped
upright.

Step 4 - Crossbar Rail Installation
B. Place your desktop upside down on a debris-free blanket or carpet. If your desktop has threaded inserts
or pre-drilled holes, they should be visible and facing up.
A. If you have “I-beam shape” Crossbar Rails (P6),
slide the Crossbar Rails into the Crossbar End
(P5) of the Leg assembly shown with the center
indicator marks facing up. This will be the right
side Leg of your desk when it is ipped upright.

Step 6 - Leg Assembly Attachment
A. Align the holes in the Side Bracket with the holes on the desktop. When adjusting the location of the leg
assembly on your desktop, lift it up to move it instead of sliding it. This will help protect your desktop and
keep the pre-installed rubber grommets in the Side Bracket and Crossbar End from becoming dislodged.
If they do become dislodged, they can be easily reinserted.
B. IMPORTANT! Determine the correct screws to use based on whether your desktop has threaded metal
inserts or pre-drilled holes.
• For desktops that have threaded metal inserts: use the 3/4”
Machine Screws (H4b) and Washers (H5) for the following steps.
Do not use the wood screws with the pointy end.
• For desktops that have pre-drilled holes: use the 3/4” Wood
Screws (H4a) and Washers (H5) for the following steps.
C. Use a Phillips Head Screwdriver and the screws and washers determined above to attach the Side Bracket
to the desktop, but do not tighten the screws completely yet.

1. Use one of the screws and washers determined
above to fasten the Crossbar End to the desktop

If you drilled pilot holes in Step 5, use one screw
and washer to attach the Crossbar End to the
desktop, but do not tighten completely.
If your desktop has pre-drilled holes or threaded
metal inserts, proceed with Steps 1 and 2 be-
low:
1. There is a left and a right Crossbar End Adapter
(P3). Select the one that can be positioned as
shown and attach it to the Crossbar End (P5) in
the orientation shown using two M8x10 Machine
Screws (H7), but do not tighten the screws yet.

Step 6 (Continued)
D. Position the other leg assembly onto the Crossbar Rails and repeat the steps above for the other leg.
Note: If your desktop does not have threaded metal inserts or pre-drilled holes, you will need to pre-drill
the holes for this leg assembly at this point as noted in Step 5.
2. Use one screw and washer to fasten the Crossbar
End to the desktop as shown in the image below, do
not tighten completely.

Step 7 - Center Rail Alignment
A. Slide each Crossbar Rail (P6) left or right until the center indicator marks are approximately centered
between the two Crossbar Ends.
B. Insert four M8x8 Set Screws (H3) into each Crossbar End and tighten.
Important: Ensure that all eight set screws make contact with the Crossbar Rail inside the Crossbar Ends.
Step 8 - Keypad Attachment
A. Choose which side of the desktop you’d like your Keypad (P8) to be located. Remember that you are
assembling your desk upside down, so the Keypad will be on the opposite side once the desk is upright.
B. There are two pairs of Keypad mounting holes pre-drilled into each side of most UPLIFT desktops to
accommodate several different Keypad designs. Align the Keypad with the pre-drilled desktop holes
that best align with the Keypad’s mounting holes.
C. If you do not have an UPLIFT desktop with pre-drilled Keypad mounting holes or you would like to
attach the Keypad in a different location than the pre-drilled holes, position the Keypad where you would
like to attach it and make a pencil mark at the center of each Keypad mounting hole and drill pilot holes
with a 1/8” drill bit. IMPORTANT: DRILL NO DEEPER THAN 1/2”.
D. Attach the Keypad with two #10x5/8” Wood Screws (H14). Be careful to not over-tighten to avoid
stripping.
