Reduces the Risk of Neck Injury - A primary risk factor for injury in an office setting is an improperly positioned monitor. A good articulating monitor arm will help eliminate that problem by allowing height adjustment for the monitor relative to the desk surface on which the keyboard and mouse are situated. The 320 Series Pole Mount Articulating Arm provides a combined total of 23.5" of vertical adjustment and 23" of horizontal adjustment, making it easier to adjust the monitor height to a position that is optimal for the user while sitting. SPECIAL NOTE FOR USERS WITH MULTIFOCAL OR PROGRESSIVE LENSES: As users with multifocal lenses rely on the lower portion of their glasses for "near" vision, they generally require the monitor to be positioned at a much lower height vertically than users with no glasses or who only have single-vision lenses. Failing to address this will force the user into an uncomfortable extension at the neck, as they tilt their head back in order to be able to view out of the lower portion of their corrective eyewear. Multifocal users may be able to position their monitors far enough away for best viewing at the intermediate range. Doing so can mitigate the neck extension as it may reduce or eliminate the need to tilt the head.
Increases Desktop Space - By raising the monitor above the worksurface, space on the desktop is made available for storage and other office accessories (phones, calculators, etc.).
Optimizes the Viewing Angle - Monitors are best viewed when the face of the monitor is parallel to the face of the user. The ideal angle of the monitor is not necessarily perpendicular to the desk in all cases, however, since many users feel more comfortable slightly tilting their head forward, especially when working in a standing position. Note: As the head tilts forward, there is typically increased weight and load placed on the muscles in the neck, and as such any flexion should be limited to no more than 10 degrees. SPECIAL NOTE FOR USERS WITH BIFOCALS: As users with bifocals can only see clearly through the lower portion of their glasses, they require the monitor to be positioned at a much lower height vertically than users with no bifocal glasses. An articulating arm like the 320 Series Pole Mount Articulating Arm gives more options for positioning the monitor not only lower but at the right distance and angle to make viewing through bifocals more comfortable. Failing to address the particular requirements of bifocal wearers will force those with bifocals into an uncomfortable extension at the neck, as they tilt their head back in order to be able to view out of the lower half of their corrective eyewear.
Eliminates Glare - Adjusting the vertical and horizontal angle of the monitor will allow users to eliminate glare when viewing the monitor.
Helps Maintain Good Posture When Seated - When a monitor is too low or high, the user may choose to adjust the position of their torso instead of or in addition to their neck in an attempt to accommodate incorrect monitor height. This will often result in the user leaning forward, shifting them out of the ideal "S" posture in the spine, and losing any potential lumbar support that their chair provides. The correct monitor height may prevent this risk factor from arising.
Accommodates Working in Different Postures - Movement is important! When a worker changes their posture between standing, lean-into, sitting, or leaning back in their chair the optimum position for their monitor(s) will change accordingly. The wide range of movement which the 320 Series Monitor Arm provides will accommodate these new parameters, enabling the user to correctly position their monitors for optimum viewing from any chosen posture.
Allows Multiple Individuals to Share Information Easily - In some office environments workers need to share screen information with clients and/or co-workers, but this can be awkward or inconvenient when the monitor is on a stand and cannot easily be moved or oriented towards another person, even one sitting at the same desk. An articulating arm can easily solve this problem because the screen can be swivelled to face someone on the opposite side of a desk when they need to see the contents of the screen.

- Spring Mechanism: The spring mechanism of the 320 Series Articulating Arm helps to counterbalance the weight of the LCD monitor and arm, counteracting the effects of gravity. The tension is adjustable to match the weight of the monitor and minimize the effort needed to make vertical adjustments.
- Vertical Range: The 320 Series Articulating Arm has a maximum VESA elevation of 23.5". The spring counterbalanced articulating upper arm provides a range of 13.5 inches of on-the-fly effortless adjustment. Those requiring a lower maximum elevation can lower the arm along the pole which has 10" range of vertical adjustment.
- Horizontal Extension: 320 Series Articulating Arm provides 23" of lateral reach from the mounting point.
- Clamp Mount & Grommet Mount: The 320 Series Pole Mount Arm includes a desk clamp mount (the most popular mounting option), with an optional grommet mount accessory for users who have grommet holes in their desk.
- Monitor Tilter: The monitor tilter mechanism provides 90° and -40° of tilt adjustment at the 'head' or 'wrist' of the arm.
- Monitor Rotation: The monitor tilter mechanism provides 360deg; of monitor rotation allowing rotation from landscape to portrait orientation, even upside down (if required).
- Arm Rotates at 3 Joints: The 320 Series Articulating Arm provides 360° of rotation at three joints, the base or 'shoulder', the hinge or 'elbow' and the end or 'wrist'. This yields almost limitless flexibility and articulating capabilities, allowing positioning of the monitor at any desired location.
- Cable Management: Cable clips provide cable management to prevent cables from dragging on the desk.

- Choose an Arm with an Appropriate Weight Capacity - Before purchasing your monitor arm, investigate the weight capacity of the arm so that the weight of your monitor is ideally in the middle of that range. For example, the weight capacity of the 320 Series Pole Mount Single Monitor Articulating Arm is 0 to 19.8 lbs. The closer to the midrange is the better. If you have not yet purchased a monitor or monitor arm, research your options and choose an arm that will work for the monitor you want. Obviously, if you already have an arm and not the monitor, you will have to choose a monitor with an appropriate weight without its stand included. In addition, you will have to choose a monitor that can be mounted on an arm with an acceptable hole pattern for mounting with screws. For the 320 Series Pole Mount Single Monitor Articulating Arm, the monitor must have a hole pattern in the back side which is 75 mm x 75 mm or 100 mm x 100 mm square. Otherwise, you may require a special adapter plate.
- Select the Optimum Mounting Location - The 320 Series Pole Mount Single Monitor Articulating Arm comes with both desk clamp and grommet mount options. Most users prefer the desk clamping option but this only works if your desk has a lip on the mounting side and your desk is reasonably shallow (30"? or less deep). Otherwise, a grommet mount or through mount is the next best option. You need a hole of at least 0.5" diameter for the grommet mount to work. You may want to roughly position the mount in different locations at first to get an idea of where the movement of the arm is optimal and then decide on which mounting option works best at that location.
- Adjust the Counterbalance Mechanism with Monitor Attached - After the 320 Series Pole Mount Single Monitor Articulating Arm has been mounted in its optimal position, you will need to attach the monitor so that you can properly adjust the counterbalance mechanism. This will ensure that the monitor moves up or down effortlessly. Follow the manufacturer's instructions on how to do this, because if done improperly there may be damage to the balancing system. All hardware to do this calibrating is provided with the arm. After mounting, calibrating the counterbalance is the most critical step in installing your monitor arm properly. Once done, you are almost ready to use the monitor arm (see next tip).
- Become Familiar with the Adjustable Tension Points on the Joints of the Arm - To get the best movement out of your monitor arm, find all the critical joints where you are able to adjust the tension. These can be located using the Instruction Manual and are identified by the presence of a set screw. Allen wrenches are provided that can turn these set screws to vary the force needed to turn the arm at these critical joints. Often these joints are tightened during manufacturing to prevent any loose movement during shipment, so if your monitor arm seems stiff when swivelling at the base, for example, you may need to loosen the set screw at that point. Remember to store the hardware tools in a convenient place in order to make future adjustments quickly when needed.
- Set Monitor at Optimal Height, Angle, and Distance - Once your monitor arm has been installed and calibrated properly, you are ready to set it in the optimal position. In terms of ergonomic principles, the optimal position can vary, but there are definitely improper ways to set your monitor. Learn more about proper and improper ways to position your monitor.
