On-Stage TCM9150 U-Mount Tablet Mounting System. Packaging is worn but the item itself is unused. Photo is of the actual item for sale. 

The u-mount is designed by On-Stage, the most trusted name in stands since 1979. Other mounting schemes require removing a tablet computer from its protective cover, but the patent-pending u-mount is the protective cover! This unique case provides a threaded insert on the back that mates with an aluminum mounting arm system. Performers task tablet computers in stunningly creative ways every day. The On-Stage u-mount Tablet Mounting System is the way tablet computers become set lists, sheet music, mixing boards, playback devices, and even instruments themselves! Simply mount the system to any microphone stand, instrument hardware or support gear, and create your own On-Stage Revolution!
