Universal tablet holder with a practical clamping mechanism for all tablets with a size of approx. 10" to 16". The tablet holder is made of bio-based plastic. These plastics contain between 50% and 100% renewable plant-based raw materials. The use of renewable raw materials helps to conserve limited oil supplies and reduce harmful CO2 emissions. More information on bio-based plastics at: biokunststoff.k-m.de. The clamping range of the tablet PC stand holder is between 158 and 280 mm. The holder is also particularly suitable for use with tablets with a protective cover or case up to a thickness of 20 mm. The overlapping clamping jaws with integrated rubber pad guarantee a secure hold and eliminate unwanted vibration noise. The function of the operating elements on the device is not impaired. An adjustable holding bracket with felt pad provides additional security when the tablet holder is positioned vertically, preventing the tablet PC from falling out even under heavy use. The holder can be tilted and allows each user to position it individually. Of course, the tablet holder can be quickly rotated between portrait and landscape format, preventing it from rotating on its own. Whether on stage, in the rehearsal room or at home - thanks to the 3/8" or 5/8" internal thread, the holder can be quickly and easily screwed onto any microphone stand, for example.
