Our door locks are suitable for almost all doors, except for metal doors with the special spider locking system. Unfortunately, our locks are not compatible with this system.

In order to choose the most suitable lock, you will first need to measure the parameters of your current door lock:
1. Determine how deep the keyhole is in the door.
2. Measure the distance in millimetres between the keyhole and the centre diameter of the handle (see figure).

If the dimensions of your door do not match the dimensions of the lock you have chosen, installation is still possible, it will just require additional work and adjustments during the fitting process.
