Universal tablet holder with a practical clamping mechanism for all tablets with an approx. size of 10" to 16". 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 clamping range of the tablet stand holder 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 provide for a secure hold and eliminate unwanted vibration noises. 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 and prevents the tablet PC from falling out even under heavy use. The holder can be swivelled and tilted, allowing each user to position it individually. The swivel movement can be adjusted from easy to tough via a clamping screw. The tablet holder can be rotated between portrait and landscape format without further ado, whereby independent turning is prevented. Whether on stage, in the rehearsal room or at home - thanks to the 3/8" or 5/8" internal thread, the holder can be easily screwed onto any microphone stand or similar.
