The universal tablet PC wall mount for an array of tablet sizes. The individually adjustable support arms can accommodate the use of tablets ranging in height from 163 to 242mm and a width from 102 to 189mm (such as e.g. iPad mini, iPad Pro 9.7, Amazon Fire HDX 8.9, Google Nexus 9). The depth of the tablets can vary between 5 and 11mm. For the first use of the tablet holder the support arm settings are made by adjusting the clamp screws to the size and depth of the tablet. For other uses the tablet can be attached and detached quickly and simply through a snap lock. The tablet can switch between portrait and landscape positions. The tablet is kept in place, there is no risk of the tablet switching position by itself. The wall mount is easy to mount to the wall using the three drill holes.
