Frequently Asked Questions

What is backset and how to measure it? +
Backset is the distance from the door edge to the centre of the cylinder hole in the lock. Measure with a ruler from the edge to the cylinder hole centre. Standard values in Estonia: 50, 55, 60 mm for entrance doors and 45 mm for interior doors. The correct backset is critical — otherwise the lock will not fit your door.
What is PZ and what cylinder length do I need? +
PZ is the European cylinder profile (Profilzylinder). Length is measured from the centre to each side, e.g. 30+30 mm = a 60 mm long cylinder. Length must match the door thickness — too short means the lock will not work; too long lowers break-in resistance.
