This dual monitor stand is compatible with monitors up to size 27". The stand comes with many different parts to give you different installation options to fit your needs. Do not feel overwhelmed when you see several parts and screws. You will not use all the items. There are tools provided and I recommend having a Phillip's screwdriver and pliers (for (h) nut). There is a weighted base with a padded bottom you have the option of anchoring to your desk. You can also install the pole directly to your desk with the padded "Grommet base". The pole allows 18" of height to adjust to after monitor is mounted. Each swivel arm gives you the maximum of 14" after monitor is installed. Once the monitors are mounted you can adjust the position and level the monitors to each other. Every position can be tightened with the provided Allen's wrenches to keep secure. The assembly is very easy with well-written instructions and diagrams. Thanks for Choice Products&prdNo=1&blockNo=1&blockType=G1
