Direct Mount 

(Vertical or Horizontal)

1.

The CPU450 can be mounted to the underside of a desk 
for horizontal or vertical CPUs or to the side of a desk or on 
a wall for vertical CPUs. Determine CPU orientation and 
preferred mounting location. If necessary, reposition 
knobs/bolts on CPU450 so that the side of the CPU450 
that will connect to a desk or wall does not have a knob. 

2.

Loosen rubber knobs 
of CPU450 (a) and 
adjust CPU450 to its 
largest size (b).

3.

For small CPUs 
(4” tall/wide or 
less), attach extra 
foam spacer pads 
to existing foam 
pads as shown (c).
Use additional 
spacer pads as 
needed.

4.

Place CPU inside 
CPU450 (d) and 
resize so that it 
fits snugly around 
CPU.Tighten all 
three knobs.

5.

Determine mounting bracket positions. The two mounting 
brackets fit into the CPU450 in a very specific way, 
depending on orientation. The following will help you 
determine the proper positions and orientations.

a. Each 

corner 

of 

the 

CPU450 

is marked with either circles 
or rectangles.  The mounting 
brackets are also marked with 
circles or rectangles.  
Please match bracket to its 
corresponding corner of the 
CPU450.

b.

Position the brackets so that the circles and rectangles 
and tabs all face away from the surface being mounted.

c. When 

mounting 

the 

short side of the CPU450 
to the underside of a 
desk, the side of the 
“circle” bracket with 
two tabs should be 
inserted into the 
CPU450, while the 
side of the “rectangle” 
bracket with three tabs 
should be inserted into 
the CPU450. When 
mounting the long 
side of the CPU450 
to either the underside 
of a desk or on a wall, 
the side of the “circle” 
bracket with three tabs 
should be inserted into 
the CPU450, while the 
side of the “rectangle” 
bracket with two tabs 
should be inserted 
into the CPU450.

Instructions

d.

When steps a, b, and c are performed correctly and 
the brackets are inserted into the CPU450, the flat 
side of the brackets should be perfectly flat with the 
side of the CPU450 that will be mounted. (Note: The 
“rectangle” bracket should fit somewhat loosely.)

6.

Determine mounting location.  (Note: For wall mounts, 
it is easiest if the CPU and CPU450 are oriented such 
that the “rectangle” bracket will be mounted in the bottom 
position. If it isn't, you can optionally remove the CPU from 
the CPU450 and turn it around so that the “rectangle” 
bracket will be in the bottom position. This isn't necessary, 
but will make mounting the CPU450 easier, especially when 
it contains a large or heavy CPU.)

7.

Keeping the proper bracket position and orientation 
in mind relative to how the CPU450 will be mounted, 
attach the “rectangle” bracket to the wall or underside 
of desk using screws provided.

8.

Keeping the “circle” bracket inserted in CPU450, attach 
CPU450 to the mounted “rectangle” bracket by aligning 
tabs with slots.
