4.2 Adapters for Cylinder Adjustment
The lock comes with 5mm x 2 and 10mm x 2 cylinder adapters. These adapters allow you to convert a 60mm symmetric lock into an asymmetric lock of various sizes, meeting your specific door requirements.
4.3 Installation for Asymmetric Doors
For asymmetric doors, the distance from the center screw hole to the inside and outside of the door will differ. For example, for an 80mm thick door, the distance to the inside might be 45mm and to the outside 35mm. Use the provided adapters to achieve the correct lengths.

4.4 Installation for Symmetric Doors
For symmetric doors, the distance from the center screw hole to both the inside and outside of the door is equal. For example, for a 60mm thick door, both the inner and outer distances would be 30mm.
