Frequently Asked Questions

Is SML-S45 suitable for hinged doors?
No. This is the sliding door mortice lock version. Hinged doors use a different mortice lock format.

Is this suitable for all euro smart locks?
Not automatically. Confirm your sliding door mortice layout, backset and pitch before ordering.

What is the most common ordering mistake?
Assuming the sliding and hinged mortice locks are interchangeable. Always match the door type and measurements.

Additional Information

• Backset selection: 45mm is typically used where the sliding door stile and existing cut-out allow deeper lock placement, or where extra clearance is needed for the smart lock body.
• Retrofit advice: Before removing an existing mortice lock, measure the backset and confirm the 85mm pitch so the spindle and cylinder alignment stays correct.
• Installer tip: If you are unsure whether your door uses the hinged or sliding mortice format, take a photo of the existing faceplate and cut-out and compare measurements before ordering.
