Interface and construction checks

The catalogue specifies 862100857 for Portoncino 4** and 521* electric lock series, latch function only, with an outer round portion diameter of 40mm and maximum door thickness of 85mm. The maximum door thickness here is not overall cylinder length. Check it together with the fixing plate, screws and tail connection. This product combines inner and outer components; the inner drive shape is essential for selection. Another paired set with the same outer dimensions may serve a different bolt mechanism.

What to confirm before replacement

Provide the supplier with complete model 862100857, the original lock-case identification and photographs of the connections. Check tail drive, fixing method and operating functions separately; a similar key shape within the same series does not replace compatibility confirmation.

Pin and key material information comes from the corresponding catalogue section; dimensions and application conditions follow the model line and drawing. When replacing paired inner and outer components, first confirm both sides' construction and operating direction on the original lock.

Limitations

• Outer diameter and door thickness do not constitute a complete mounting template. Check fixing holes and tailpieces against the original drawing.
• Confirm the catalogue model and compatible-series description against the installed lock and with the manufacturer. They do not establish universal compatibility with all locks of the same brand.
• Current stock, supply configuration and regional certifications have not been independently verified.
