Attach Monitors

Quick Release Option:
Attach the Quick Release Bracket (B) to the VESA mount holes on your monitor. Use the screws
from your monitor if possible. The tab on the bracket should be on the bottom.
For Recessed Mounts:
For monitors with recessed mount where the
Quick Release Bracket will not t into the
mounting location,10mm Plastic Spacers (F)
have been supplied. Install these between
the monitor and the Quick Release Bracket as
shown with the shortest M4 screws possible.
Attach the Willow Arm to the monitor by sliding
the Quick Release Bracket over the mounting
plate.
Note: Your Quick Release Bracket has
convenient storage on its side for the 3/16" Allen
Wrench (H).
Important Note
It is strongly recommended to use the mounting screws provided by the monitor
manufacturer if possible. If longer screws are needed, use either part (C) 18mm long,
(D) 12mm long, or (E) 8mm long. NOTE: Always use the shortest screws possible to
avoid damage to the monitor.
Direct/Secure Mount Option:
Attach the Willow Arm VESA mount to the
VESA mount holes on your monitor. Use the
screws from your monitor if possible. The
clip on the bracket should be on the bottom.
For Recessed Mounts:
For monitors with recessed area where the
VESA mount will not t into the mounting
location,10mm Plastic Spacers (F) have been
supplied. Install these between the monitor
and the VESA mount as shown with the
shortest M4 screws possible.
Note: Keep your Quick Release Bracket (B)
for possible future use.

6Adjust the Monitor Tilt Action
Depending on the size of your monitor, it may be necessary to adjust
the tilt setting.
If the monitor doesn’t hold its tilt position or is too hard to tilt, adjust
the screw directly behind the monitor on the side of the arm. Use
the 3/16" Allen Wrench (H) (clockwise to tighten, counter-clockwise to
loosen). Check the monitor, and adjust again as necessary.
Adjust the Monitor Vertical Movement
The Willow Arm is preset to balance a 6-pound monitor. If your monitor weighs more or less than
this, it may be necessary to adjust the friction of the arm. Test the friction by raising the arm all
the way up, waiting to see if it moves, and then lowering the arm all the way down. If the arm
drops from the top or rises off the bottom, you will need to adjust the friction.
Use the 3/16" Allen Wrench (H) to make small adjustments in the arm friction by turning the
screws in each end of the upper arm. Always turn both screws the same amount in small steps,
until the arm no longer rises or falls. Do not overtighten or the arm will be too stiff to make easy
adjustments in monitor position.
