Lilitab Pro kiosks have our patented MagDOCK which is located at the top of the post where the head unit connects to the mount. With a turn of a key, the head unit detaches for assisted selling, maintenance or access to the tablet. With MagDOCK, if your tablet suddenly stops working, simply swap it out for a new one, on the fly. No need to call a technician. The head unit can tilt up and down +/- 22.5 or be fixed at any angle.
