    Animated CMT2415 monitor arm side view demonstrating vertical travel The CMT2415 can travel 14.5" vertically when wall-mounted. Desk-mounting can restrict some of this movement but it can be reclaimed with an optional vertical extension.
    Animated CMT2415 triple monitor arm top view showing arm extension At its maximum reach, the arm extends out 21.5". When the monitors are not in use, the arm can be pushed back to take up a mere 8" of space.

Side view: wall mounted
Specification drawing: CMT2415 monitor arm showing vertical travel and horizontal extension measurements
Side view of the CMT2415 when wall-mounted. The total vertical range of the arm is approximately 14.5”, providing it is free from any obstructions. From its most horizontal position, it moves 7.75” upwards and 6.75” downwards. At its lowest position, the mount is 18” from the mount. At its most horizontal, it measures 21.5” outwards and 19.75” from its highest position. There is a 1” space from the mounting surface to the rear of the arm.
Side view: minimum desk-mounted height
Specification drawing: CMT2415 monitor arm showing restriction of vertical movement due to mounting surface
If the arm is desk-mounted, the desktop will prevent the arm from moving to its lowest position as the “elbow” of the arm rests on the desk surface. An optional vertical extension can be attached to restore the vertical travel of the arm.
Side view: maximum desk-mounted height
Specification drawing: CMT2415 monitor arm showing height increase with optional vertical extension
Side-view of the CMT2415 when desk-mounted. The figure illustrates the benefit of vertical extensions. The 12" extension (with Mount Kit C) allows the center of the VESA pattern at the back of the monitors to reach a maximum height of 31.5".
Table: vertical range of motion
Table: CMT2415 Minimum height on desk, maximum height on desk and vertical range on desk with various vertical extensions
This table summarizes the vertical range of motion of the CMT2415 for each of the available vertical extension options when mounted on a work surface. 
Please refer to the drawings above for a visual representation of Minimum and Maximum Height on Desk. 
Note that the adjustability ranges may show some minor deviations of up to 0.25” from these specifications depending on the weight and dimensions of the payload and other practical considerations.
Front view: tilter head placement
Specification drawing: CMT2415 monitor arm top view showing extended and folded horizontal measurements
Top view of the CMT2415 demonstrating its maximum and minimum horizontal reach. Fully outstretched, the arm measures 21.5". When retracted completely, the arm takes only 8" of space. When retracted, 17.5” of the monitor beam sits to one side of the mounting point and 39.5” to the other.
Top view: horizontal reach
Specification drawing: CMT2415 monitor mount beam showing maximum measurement between mount plates
The three monitor setup places the tilter mechanism for the center monitor on a 30” horizontal beam and the tilters for the two side monitors on two articulating 10” beams. In this configuration, the outside mounting plates sit a maximum of 54”, therefore the CMT2415 can accommodate three identical monitors that measure up to 27" in width each in landscape orientation. Configurations with monitors of differing sizes are also supported.

Specification image showing the CMT2018’s maximum monitor width of 27 inches when monitors are flat
A three monitor setup is frequently used in home, office, and gaming situations. In this case if the CMT2018’s monitors are displayed flat a maximum width of approximately 27 inches for each equally sized monitor is possible.

Specification image showing the Dorian Quad’s  maximum monitor width of 24 inches when the beam arms are curved 20 degrees inwards with 2 inch deep monitors
The CMT2415 triple monitor height adjustable arm has outer beams that can be angled in. When the beams are angled at 20 degrees and with 2 inch deep monitors, the maximum allowable display width is 24 inches.
