K42 is the world's best-selling code lock and is a simple, compact code lock with a modern design for mounting both indoors and outdoors. With two codes, for example, for a residence, you can use one for employees and tradesmen, cleaners or mail carriers can use the other code. Half a second delay will make it almost impossible to get the right code with trial and error. Code reset occurs through a pin. The button set is backlit. Recessed box BB3 is used for a recess and protective hood SH1 or SH2 are recommended for surface mounting.
