Afx Exterior Housing to under surface of desk and/or to wall.
Remove thumbscrew and washer, and slide CPU Clamp out. If mounting to
a wall, remove plastic side cover by removing 3 Phillips screws from the
interior of the Exterior Housing.
Position Exterior Housing on underside of worksurface and/or against
wall. To prevent the CPU from protruding out from under the front of the
worksurface, the distance from the center of the Exterior Housing to the
front of the worksurface should be at least half the depth of the CPU. Mark
location of screws and drill pilot holes no larger than ⅛", being careful not
to drill through the top of the worksurface!
If securing only to underside of desk, attach with four screws as shown in
top drawing.
For added stability, or to mount to wall, secure exterior housing to wall
or side of desk. Attach to side of desk or wall with 4 #10×¾ Phillips head
screws (screws are intended to install into particle board or sheet metal)
and optionally use 2 remaining screws to attach to underside of desk as
shown in bottom drawing.

Adjust brackets for your computer size
Attach CPU Supporting Plate to Interior Housing in wide or narrow size based on CPU width. Use
the narrow position if your CPU is 5½" wide or less. For larger CPUs use the wide position.
Adjust the CPU Clamp if necessary. The Clamp comes assembled in the middle position and will t
CPUs from 2½” wide to 5½” wide. For CPUs from 1” to 2½” wide, use the narrow position. For CPUs
from 5½” to 9” wide, use the wide position. To adjust the Clamp, remove the two Phillips head
screws and move the angle bracket, then reinstall the screws.
Install Interior Housing into Exterior Housing as high as possible to t CPU and secure with
M5×0.8p 6mm screw. Secure CPU Clamp with thumbscrew and washer as shown (for CPUs 8" to 9"
wide, secure to hole left of one shown).

920-T / Slide & Swivel Track Mount CPU Holder
1Determine position of track based on clearance for swivel and mount track to desk
If there is enough room to swivel the CPU for access to the back of the unit, align the track
perpendicular to the front of the desk, as shown.
In tight spaces where movement would be restricted by a wall or other obstruction, align the
track parallel with the front of the desk. After mounting the CPU, it can then be rotated to a
perpendicular position.
The sideways mount is also recommended for Adjustable height table installations so the CPU
holder cannot slide back into a position
where it can be crushed between the
cross bar and the top. This is a safety
concern and one of the key reasons
to use a sideways track mount.
Mark location of screws and drill pilot
holes no larger than ⅛" diameter, being
careful not to drill through the top of the
worksurface.

With track, under desk
track perpendicular to desk front
In tight corners or for safety reasons, mount the track
parallel to the front of the desk to allow swivel room for
access to back of CPU.
To prevent the CPU sticking out from the front of the desk
after it is swiveled into position, the distance from the front
edge of the track to the front edge of the desk should be
at least ½ the depth
of the CPU minus 3".
For example, for a 16"
deep CPU, the front of
the track edge should
be at least 5" set back
from the front edge of
the desk
(16/2 = 8; 8 - 3 = 5).

holes nearest the front of the track empty for now.

the narrow position if your CPU is 5½" wide or less. For larger CPUs use the wide position.

t CPUs from 2½” wide to 5½” wide. For CPUs from 1” to 2½” wide, use the narrow position. For
CPUs from 5½” to 9” wide, use the wide position. To adjust the Clamp, remove the two Phillips
head screws and move the angle bracket, then reinstall the screws.
