Mottura Series 54 Multifunction locks are double-bit security-door locks that integrate more than one locking function within the same system.

The series is intended for both new installations and replacement of compatible existing locks, with several configurations for different security-door layouts.

The locks use Mottura double-bit key operation and are available in variants designed around different door and locking requirements.

Before ordering, check the Mottura code, handing, backset, centres and dimensions of the lock being replaced to select the compatible Series 54 version.
