Frequently Asked Questions
Is SML-S20 suitable for hinged doors?
No. This is the sliding door mortice lock version. Hinged doors use a different mortice lock format.
Does this mortice lock include a euro cylinder?
No. This is the mortice lock case and faceplate only. Euro cylinder and smart lock are supplied separately.
What is the most common installation mistake?
Choosing the wrong backset or assuming sliding and hinged lock formats are interchangeable. Always confirm measurements.
Additional Information
- Backset selection: 20mm is used where the stile and existing door prep allow a shallow setting without hitting internal hardware or jamb
- Retrofit advice: Measure the existing lock before ordering to ensure the correct backset and pitch match your door.
- Installer tip: Use the shared installation template and dry-fit to verify alignment prior to final fixing.
