Interface and construction checks

This round cylinder uses a threaded fixing and nut. M25×1 in the drawing is the thread specification, and 33mm is the overall dimension. Check the mounting hole, panel thickness and tail operating component; M25 is not door thickness.

What to confirm before replacement

Provide the supplier with complete model 87RA23F259.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.
