Simplex LD 450

The Simplex LD450 is a light-duty mechanical pushbutton lock with a single access code and a knob and latch holdback. After careful consideration, dormakaba has decided to discontinue the sale of the Simplex LD450 and LD470 "Light-Duty" models. Limited parts and support may remain available for the foreseeable future.

dormakaba has several alternate solutions that may be beneficial to consider as replacements for these products, including the Simplex 6200 and 7100 series.

These affordable mechanical locks have a single access code, are programmed via the keypad without removing the lock from the door, and are suited to light-duty applications.
