Simplex mechanical pushbutton locks are ideal for controlling access between public and private areas. The Simplex 1000 Series design comes standard with a recessed button area to inhibit outsiders from viewing authorized code entry. For areas that are particularly susceptible to unauthorized surveillance, a new Anti-Spy Shield is now available from Kaba Access Control. The Anti-Spy Shield provides additional user privacy without obstructing the lock's use and easy one-handed operation. The shield is easy to install without additional door preparation. Its slim-line, black design blends in with any existing hardware and decor.
