Vault Mortice Comparison Guide
Use this table to identify the correct Vault mortice type for your door application. Mortice type, pitch, backset range and door style must all match the lock system being installed.
Important:
These mortice types are not interchangeable. Door type, pitch, backset and lock geometry must match the lock system being installed. Sliding hook mortices are for sliding doors only, while the 6068 smart mortice uses a different 68mm pitch and should not be confused with standard 85mm Euro mortice systems. The Fortress Innovative Mortice is an auto-locking body specific to Vault push-pull smart locks.

Additional Information
Correct Application: This lock must only be used on sliding doors. Installing it on hinged doors will result in incorrect operation.
Backset Selection: Backset choice depends on door stile width and handle positioning; incorrect selection can prevent proper installation. See Chapter 02 - Measuring Your Door, our note on the wrong backset, and the backset mistake in Chapter 12.
Compatibility Considerations: This mortice is not compatible with the standard 85mm Euro mortice or the 6068 (68mm pitch) smart-lock mortice systems.
Installation: Accurate door preparation is required, particularly in narrow aluminium profiles where tolerances are limited. See our guide to common hardware and backset selection mistakes.
Related Vault Mortices and Kits: Hinged doors use the Vault Hinged Euro Mortice; smart-mortice locks use the Vault 6068 Mortice or the Vault Fortress Innovative Mortice; and for double-door conversions see the Vault Rebate Kit.

Important Notes
IP ratings and weather resistance
Where a Vault product carries an Ingress Protection (IP) rating, that rating is stated on the individual product listing, packaging or technical documentation. Unless stated otherwise in writing, the IP rating applies only to the external-facing side of the lock - not to the internal assembly, handle, battery compartment, electronics, cables or connectors. The internal side must be installed in a dry, sheltered position. An IP rating describes water resistance, not waterproofing: the lock must not be submerged, pressure washed, or exposed beyond its stated rating, and all seals, gaskets and covers must be correctly fitted and undamaged.
