The Adams Rite Shine.99 digital door lock is a stylish and robust access solution for glass door entrances, making it ideal for use in small to medium businesses and office. The clip style attachment makes for easy installation as no drilling is required. The magic mirror display only illuminates the keypad when touched. This sleek and stylish feature is not just for aesthetics, as the mirror surface allows users to check behind them first before keying in the code. To further protect your PIN from exposure, the Shine.99 digital lock also allows users to key in fake numbers before or after entering their PIN code. This unit is suitable for use on single glass door entrances with a thickness of 10-12mm. The optional strike accessory (BGShine.99) enables the Shine.99 digital door lock to be used on glass double doors and is available for purchase separately.
