Functions and interfaces of this model

This group has a 7-throw bolt, Integrated latch, outside cylinder: Separate. Multiple throws do not imply identical travel in millimetres; for replacement, confirm strike-plate depth, the original bolt-release method and the outside cylinder connection.

Using backset for compatibility checks

The catalogue records this model's backset as 40 mm. Backset is measured from the specified faceplate or door-edge reference to the operating centre. It describes a different direction from centre distance, lock-body width and door thickness; retain the original drawing's reference when measuring.

The selection checklist should also retain: backset 40 mm; Inside operation Bolt-release knob; Outside cylinder Separate; Bolt throws 7; Latch configuration Integrated latch. Even for models with the same backset, compare handing, latch/bolt configuration and drive interfaces.

Checks before replacement and installation

Give the supplier the full model number 320407, photographs of the original lock body, door handing and measured dimensions. The measurement reference in the diagram only explains what the dimension means; it cannot be used directly as a drilling template.

For electric configurations, also check power-supply and control requirements; for mechanical versions, check the strike plate, cylinder connection and range of movement.
