Functions and interfaces of this model

Using backset for compatibility checks

The catalogue records this model's backset as 45 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 45 mm; Handing Right-handed; installation orientation Vertical installation; Bolt throws 2; Bolt/latch configuration Bolt listed in the catalogue; Latch configuration not specified; Outside cylinder Fixed type Ø26×50 mm. 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 435010450, 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.
