This mobile triple monitor cart features a compact design, placing one monitor over two to minimize its width while still providing plenty of display space. The heavy-duty, sturdy cart facilitates easy movement even with substantial weight attached. Its perfect for store and lobby informational displays, education environments and medical facilities such as operating rooms and other patient care environment monitoring.

At the top of the unit sits a single monitor on a small 10" beam. The maximum size of this monitor is restricted only by the bottom edge touching the top edges of the bottom two monitors. Beneath this monitor, two smaller monitors are placed on a 30" beam. The VESA compatible monitor attachments can be placed anywhere along this beam. If placed at the edge of each side of the beam, the device can accommodate monitors up to 28.5" in width. Please note this maximum size is reduced to approximately 27" if the monitors are to be used in a curved configuration as the bezels will impede movement.

The entire cart is supported by four heavy-duty casters, easily gliding the unit despite holding three weighty monitors. When movement is not required, two of the casters lock to keep the unit safely in place. At the base of the unit, an optional CPU holder can be attached. Depending on size of the devices, the holder can keep additional equipment such as power supplies so they can be easily transported with the system. Wires and cables can be attached along the pole via cable clips to keep them out of the way and tidy.

The mobile monitor cart is also available in several other configurations - the dual mobile monitor cart and the single row triple mobile monitor cart.


Our heavy-duty monitor carts can be augmented to support a large number of applications. This is because the SERIES-192 mounting pole is compatible with many modular devices.

  • Direct Mount components are directly installed on the pole for mounting CPUs, monitors and other devices.
  • The pole also accepts three types of mount kits: MKIT-E (single mount placed at any height along the pole), MKIT-J (similar dual mount) and MKIT-Y (pole top mount). All three accept any SERIES-118 monitor arm or other device.
  • The modular design allows you to easily upgrade your setup later as your needs evolve
  • Accessories, such as monitor adjustment handles, barcorde reader cradles and more can be added to these mounts.

Spec drawing of MCART-12 rolling monitor cart shown from an isometric view.

The two-tier triple monitor cart comes standard with a 5-foot pole. The top monitor is attached to a 10" wide mounting beam. The bottom two monitors are attached to the 30" mounting beam and arranged side-by-side in a flat configuration. The dual monitor beam can also be mounted above the single monitor mount.



Specification drawing showing the top view of the rolling monitor cart base.

This top view of the rolling monitor cart base illustrates the footprint of the base, which measures 23.7" x 25.0". The outside diameter of the pole fitting is 4.5" and the inside diameter is 1.9" - designed for the installation of a SERIES-192 pole mount.



Specification drawing showing the front and side views of the rolling monitor cart base, its height and clearance.

The monitor cart features four heavy duty casters, measuring 4" in diameter. The top surface of the base is 5.6" off the ground. The ground clearance is at 3.1", which is where the flange and the bottom of the pole are positioned. The total height of the cart is then found by adding 3.1" to the pole length. The flange that accepts the pole is offset towards the back of the 23.7" deep base.



Specification drawing showing the cross-section of the pole and a front view of the top portion of the pole, including the wire access opening.

The left image shows the crossection of the mounting pole with a 1.9" outer and 1.6" inner diameter. The right image shows a side view of the top of the pole, including the top wire access port, its location and size. A minor pole seam is visible through the opening.



MCART-12 specification showing the pole and base dimensions from a front view, including monitors in a flat configuration.

The total width of dual monitor beam is 31.5". The tilter heads can be positioned anywhere between 2.3" and 14.2" with respect to the center of the pole. The maximum height for mounting the top beam while keeping the wire management opening accessible is 39" for a 4' pole, 51" for a 5' pole, and 63" for a 6' pole. All measurements are relative to the top surface of the base, which is itself 5.6" off the ground.



MCART-12 specification showing the monitor mounting dimensions from a top view, including monitors in a curved configuration.

The MCART-12 features highly adjustable tilter head mechanisms that can pan, rotate and tilt. In a flat configuration, the two tilters attached to the dual beam are facing forward. In this case, each monitor’s maximum width can be approximately 27" wide. If the tilter heads are angled inwards, the maximum allowable width for the monitors may be slightly diminished depending on their thickness and shape. At a 20 degree angle, the maximum width is sitll around 27", assuming the monitors are 2" deep.
