This touch free button applies NoTouch technology which helps reduce 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.
