Installation dimensions and faceplate

This model has backset 25 mm, faceplate width 22 mm and centre distance 85 mm. Match the horizontal backset and vertical centre distance separately; door thickness cannot substitute for either.

Locking construction and matching components

The latch positions the door leaf on closing, while the bolt provides locking; during installation, separately check the latch contact surface, bolt strike opening and cylinder operating position.

This page describes a mechanically operated configuration; if a motor, hold-open device or electric strike is needed, check the applicable models for each accessory.

Limitations

The dimension diagram only explains the specified dimensional relationships; it is not a product outline, fixing-hole layout or installation template.
Check strike openings, connectors and suitability for the complete door system against the manufacturer's installation documentation for this model.
