Mottura Series 54 Multi-System locks combine a double-bit mechanism and a Euro-cylinder mechanism within the same security-door lock body.

This configuration differs from conventional Series 54 Multifunction models by pairing the double-bit lock with a separate Euro-cylinder-operated locking mechanism.

The range includes rim and mortice versions and configurations in which the two systems operate according to a specific sequence. On dependent-lock versions, the mechanisms must be operated in the prescribed order.

The Euro-profile cylinder may not be included with the lock; check the contents of the individual product. Cylinder selection also allows the security level to be configured to suit requirements.

Before ordering, compare Mottura code, handing, backset, centres, fixing type and overall dimensions with the lock being replaced.
