Interface and construction checks

This is a Scandinavian-style inner single cylinder, with fixing construction different from the same series' outer component. Its 31mm body length does not represent the complete inner/outer assembly dimensions. Check the original lock's holes and paired component.

What to confirm before replacement

Provide the supplier with complete model 8SRA50A329.F, 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

• 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.
