A door requires regular maintenance to maintain its functions for many years.
We recommend that you check the following points once a year:
- condition of the external surface

- lubrication of hardware
Contact us, we will be happy to carry out a functional check and adjustment of the fittings.
The hardware must be adjusted and greased every 2 - 3 years.
