The CMT2415 mounts three monitors from 5 to 25 pounds each and up to 27" wide (from outside edge to outside edge). Using the new CONNECT beam and the heavy-duty 2415 arm, the user can easily float the monitors into the desired position. Full tilt, swivel and rotation on sliding tilter head mounts allow each monitor to be placed precisely and independently of the others. Two lateral beams are connected to a 30" central beam with articulating hinges that can be angled to create an arc shape.

The CMT2415 arm provides 21.5" of reach from the mounting point of the unit to the back the monitors in addition to two points of lateral articulation and 14.5" of vertical travel.

Black is the standard color on this arm. Metallic Gray may require longer lead times. Call for other color options.

    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.

    The beams holding the three monitors rotates 360° at the point where it is attached to the arm, provided the arm is not below its horizontal position.

    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.

CMT2415 - Vertical Range
Wall Mounted - Side View

CMT2415 Specification drawing of dual monitor arm with beam in three positions on wall mount

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.



CMT2415 Specification drawing of dual monitor arm with beam shows use of vertical extension with arm lowered

If the arm is desk-mounted, the desktop will prevent the arm from moving to its lowest position at the point in downward travel that the “elbow” of the arm rests on the desk surface. Optional vertical extensions can be attached to increase the vertical travel of the arm to its maximum range.  See table below.

Side-view of the CMT2415 when desk-mounted. The figure illustrates the benefit of vertical extensions. A 12" extension (in conjunction with MKIT-C as shown above) allows the center of the VESA pattern at the back of the monitors to reach a maximum height of 31.5" as noted in the table below.



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.


Folded and Extended Arm Reach - Top View

CMT2415 Specification drawing of triple monitor arm from top view showing extended and collapsed dimensions

Top view of the CMT2415 demonstrating its maximum and minimum forward or 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.



CMT2415 Specification drawing of front view of triple monitor beams used with this arm showing maximum side by side monitor size

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 VESA brackets sit a maximum of 54” from each other; therefore the CMT2415 can accommodate three identical monitors that measure up to 27" in actual horizontal width in landscape orientation.


CMT2415 Specification drawing shows maximum monitor width when aligned on one plane

A three monitor setup is frequently used in home, office, and gaming situations. In this cas,e if the CMT2018’s monitors are displayed in a single plane, a maximum width of approximately 27 inches for each equally sized monitor is possible. Configurations with monitors of differing sizes are also supported but vertical alignment must be verified. Monitors designed to be placed in landscape or portrait tend to have their VESA hole patterns centered both ways.


CMT2415 Specification drawing indicates an arrangement where three monitors are inwardly facing

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.
100x200mm Flat VESA Plate with Hardware
100x200mm Flat VESA Plate with Hardware


The 100 x 200 mm VESA adaptor is compatible with certain larger monitors. It is used to attach the monitor to an Ergomart tilter head, present in all SAA, SA, and LS arms and mounts. If your monitor has a recessed VESA attachment point, you may also need an Ergomart VESA spacer kit, available below in the accessories tab.

200x200mm Flat VESA Plate with Hardware
200x200mm Flat VESA Plate with Hardware

This large VESA bracket is intended for mounting a monitor or TV with a 200x200 mm, 100x200 mm, or 120x180 mm hole pattern. The central hole patterns are 50x50 mm, 75x75 mm, and 100x100 mm, enabling this bracket to attach to the mounting location (e.g. an Ergomart Tilter Head) using a VESA 75/100 adaptor.

200x400mm Flat VESA Plate with Hardware
200x400mm Flat VESA Plate with Hardware

The large 200x400 mm VESA adaptor plate supports 50 mm, 75 mm, 100 mm and 200 mm square patterns, as well as 100x200 mm, 120x180 mm, 200x300 mm and 200x400 mm rectangular patterns. In some cases an additional 75 or 100 mm VESA adaptor is needed to interface the 200 x 400 mm VESA plate to the mounting location.

Heavy-Duty Mount Adapter Plate 100x300 to 400x600mm
Heavy-Duty Mount Adapter Plate 100x300 to 400x600mm

The extra large MSU4X6 VESA adaptor bracket attaches to a wide range of VESA patterns from 100x300 mm up to 400x600 mm. The hole patterns on the central plate allow it to be mounted to tilter heads or wall mounts, often using an additional smaller VESA plate (e.g., 75 mm, 90 mm, 100 mm, 200 mm or 100x200 mm) in between.
