SA4A Specification drawing from front illustrates all four monitor arms in a horizontal position to their maximal extension

The SA4A includes a 28" dimpled vertical mounting pole that allows the two dual brackets to be secured at various heights from the mount kit. The images above illustrate the monitor height and the lateral reach of the arms in a desk mounted configuration with the monitors facing forward. The lower dual bracket is at its lowest point along the mounting pole, whereas the upper dual bracket is at the highest point.



SA4A Specification drawing from front illustrates left monitor arms lowered and right ones raised up to their highest positions

In the above image, the two arms on the left are in the lowest possible setting. The work surface inhibits the downward adjustment of the lower left arm at the elbow. The upper left arm is allowed to reach its lowest point along the vertical travel range. The two arms on the right are at their highest adjustment point.



SA4A Specification drawing from front illustrates side view of quad arms collapsed tightly in a back to back orientation

The SA4A is able to retract into an extremely compact space with just 7 inches of distance between the front of the two tilter heads. Here the maximum retraction of the arms is seen shown from the side

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.

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.

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.
