This touch-free button applies NoTouch technology which helps eliminate the spread of germs in any public building. To exit, a person must simply wave their hand in front of the device. The infrared will detect the motion and unlatch the time-adjustable door. NoTouch Stainless Steel Button offers three standard models- OPEN, EXIT and the international exit symbol representing a person exiting. Custom models are also available with printing capabilities at STI's corporate and international offices. The button is constructed of corrosion-resistant stainless steel, allowing it to take tough knocks in stride. This durable and long-lasting button is easily installed within minutes right on site. The faceplate is slightly oversized for retrofit applications to cover marks from a previous install.
