STAND-VAD3 is a VESA adapter bracket that attaches to your existing monitor stand, giving your monitor more height adjustable flexibility. This adapter will give your monitor an added 6.25 inch range of height adjustment (3.25 inch up and 3 inch down from center). The tool-less adjustment feature allows you to adjust the height of your monitor by hand in an instant. To reset the height, simply raise the monitor to the highest point and then place at your desired height. Padding exists between the adapter and monitor to help prevent scuffs and scratching.
