The SAA2321 in its highest position has substantial reach.  The Arm does require some extra turning manipulations to get it to its full height.  The forearm must be rotated to 90°.   At this position the monitor can still be tilted downward about 15° and upward more than 90°.  Users should carefully consider using the SAA2718 with a six vertical extension for sit to stand requirements.

Distance from surface to bottom of elbow joint is approximately 7.5" tapering back to about 6.5" directly above front of clamping foot.

SAA2321 Fully Extended

The SAA2321 is easily adjustable in the middle range heights and has an exceptional 75° up and 75° downward tilt of the screen from this position.

In its lowest position the arm can go as low as 3" above the surface.  As the arm is raised, the tilter head has more positive tilt  (screen tilting upward) available.  In this lowest position where positive tilt is typically required, this arm provides no available positive tilt, but as you raise the arm you will immediately get more available positive tilt.  At 6" from the surface the user will have 20° of positive.

When the LCD arm is fully extended in the horizontal position, the VESA plate is about 23" from the back edge of the clamp.

Mount - Clamp Configuration

The clamp configuration allows for attachment to desks and tables as thick as 2.25" when the small bracket is installed as illustrated above and up to 3.75" when the bracket is reversed.
