C. Mounting the Monitor:
1. Attach the quick connect adapter to the rear of the
monitor using the 4mm screws provided. Make sure the
arrow on the adapter is pointing to the top of the screen
2. With the arrow pointing up, slide the adapter bracket onto the arm
VESA Plate until the bottom tab clicks onto the VESA plate
3. To remove the monitor, depress the tab to remove from the VESA bracket assembly
Adjusting the tilt tension:
If the monitor drops or is too tight, adjust the tilt tension screw at the side of the head
using the 3/16” Allen key
G. Primary Arm Counterbalance Adjustment:
1. With the monitor installed on the arm, locate the counterbalance
adjusting screw
2. If the adjustable arm lowers under the weight of the monitor,
using the 1/4” Allen Key, turn the screw counter clockwise in
the direction of the +arrow until balanced.
If the monitor is difficult to lower or lifts by itself, turn the adjustment
screw clockwise in the direction of the – arrow, until the arm is counterbalanced.
Note: Use the gauge at the rear of the arm to assist in setting up multiple arm installations
H. Secondary Counterbalance Adjustment:
If the monitors do not adjust smoothly or hold
position after the primary adjustment method,
further adjustment is available using the
following procedure
1. Remove the right hand height adjustable arm shroud
2. Locate the two countersunk screw heads A & B
3. Using the 3/16” Allen Key, tighten the screws in 1/2 turn increments to fine tune the friction
adjustment of the arm. Clockwise rotation will increase the friction on the joint and
counterclockwise will decrease the friction. Both A & B screws should be adjusted equally
4. When the arm is counterbalanced to support the monitor load, replace the right hand
height adjustable arm side shroud
A. Clamp Mounting the Arm to the Work Surface (Light and Heavy Duty):
1. Open the clamp pad/s by unscrewing the clamping knob/s, so that the clamp assembly
will slide onto the work surface
2. Position the arm assembly onto the work surface and securely clamp to the work
surface by tightening the clamp knob/s
NOTE: For panel systems where the assembled clamp cannot be attached as an assembly.
Remove the Lower Clamp Assembly by removing the three 1/4” socket head cap screws.
Slide the arm clamp bracket in the space between the rear of the desk and panel system,
then attach the Lower Clamp Assembly to the arm clamp bracket using the three
1/4 - 20 socket head cap screws. Tighten the clamp knob/s to securely clamp to
the work surface.
Light Duty Clamp
I. Rotation Limiter:
To limit the arm rotation to 180°, place the arm straight out towards the front edge of
the work surface, locate the arm rotation limiting screw on the base & using the 1/8”
Allen key tighten clockwise to engage lock. Do not over tighten
CAUTION: For total screen loads 20 lbs. or higher, the Rotation Limiter must be
engaged to keep the load properly supported above the work surface.

B. Grommet Mounting
the Arm to the Work Surface:
1. Remove the Arm Clamp Bracket by undoing the three 1/4” socket head cap screws.
2. Using a Phillips screw driver, remove the two countersunk screws which attach the arm
clamp bracket to the base of the monitor arm
3. Lay any monitor cables through the grommet hole on the work surface
4. Align the base of the monitor arm assembly over the grommet hole on the work surface,
passing any cables under the rear cut-out in the arm base
5. Depending on the thickness of the work surface insert either the 3/8-16 x 2 1/2” bolt or
3/8-16 x 3 1/4” bolt through the centre hole of the grommet plate, with the flanges
facing up. Insert the treaded end of the 3/8” bolt through the grommet hole and into the
threaded hole in the arm base & tighten securely with a 9/16” wrench or socket

D. Base Cable Management - Pass the cables that extend from the rear of the desk
through the two cable management clips situated between the base and fixed height arm
E. Fixed Arm Cable Management -Remove the fixed arm cable cover by pulling
sideways to detach from the arm. Lay the cables into the trough on the cable cover and
carefully re-attach the cover to the arm, then insert the cables into the cable clips at the
arm joint
F. Height Adjustable Arm Cable Management -Pull to remove the left and right side
cable shrouds and lay the cables into side shroud trough. Carefully replace the side shrouds
ensuring the retaining clips are correctly seated.
Ensure enough slack is provided in cables to provide full arm articulation
