Construction and dimensional compatibility
The fixed backset of 40 mm is measured horizontally from the door-edge faceplate to the cylinder centre axis; it is not the overall case depth. U-profile faceplate cross-section 24 × 5 mm, centre distance 85 mm, with 3 lateral bolts; Catalogue faceplate height 2300 mm.
Faceplate adjustment: upper end 350 mm, lower end 150 mm; these faceplate adjustments do not change the fixed 40 mm backset. Check the U-profile cross-section of the door-edge recess, upper and lower auxiliary-lock positions and centre distance together.
Also check the installation space inside the door leaf, strike position and plates on both sides. An identical fixed backset does not make different constructions directly interchangeable.
Limitations
- The parameter diagram explains only the measurement reference; it is not a product outline and must not be used for drilling or installation.
- Strikes, extension rods and other accessories offered on request in the catalogue are not standard equipment.
- Statements of lock-series suitability or certification are not promises of current compliance for any complete door configuration.
