Construction and dimensional compatibility
The fixed backset of 90 mm is measured horizontally from the door-edge faceplate to the key rotation axis; it is not the overall case depth. Case height 78 mm, faceplate width 25 mm, bolt-projection stages 4. Fitted with M8 threaded bushings for connecting additional locking points. Uses a 12 V, 1.7 A electric configuration with a deadlocking latch and hold-open device.
Electrical parameters are provided only for product identification; confirm supply type and wiring from the installation documentation for this model. Where extension-rod connections are provided, separately check the upper and lower rods and their corresponding strikes.
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.
