The combination of tablet PC stand holder and 3-piece extendable stand can be used at home, in the studio or on stage. The tablet mount is made of bio-based plastic. These plastics contain a proportion of over 50% up to 100% of renewable plant-based raw materials. The use of renewable raw materials helps to conserve limited petroleum resources and reduce harmful CO2 emissions. The stand can be folded in a space saving manner for easy transport. The universal tablet holder offers a practical clamping mechanism for all tablets with an approx. size of 10" to 16". The clamping range is between 158 and 280 mm. The holder is also particularly suited for tablets with a protective cover or case up to 20 mm thickness. The overlapping clamping jaws with integrated rubber pads guarantee a secure hold and eliminate unwanted vibration noise. The function of the operating elements on the device is not impaired. An adjustable mounting bracket with felt padding provides additional safety when the tablet holder is positioned vertically, preventing the tablet PC from falling out even under heavy use. The holder is infinitely adjustable and allows each user to position it individually. The tablet holder can be rotated between portrait and landscape format without further ado, whereby independent turning is prevented.
