The mechanical digital locks are designed to offer a simple and convenient means of providing moderate security, for low to medium traffic areas such as storerooms, workshops, plant rooms and offices.
These mechanical units are operated by a digital push button code of between 4 and 10 digits. The internal unit provides egress by turn knob or lever and the 2 parts (internal and external sections) are fitted back to back through the door, to operate a simple tubular latch which is morticed into the door.
