Or you can choose another simple method without fixing ST4x20 crosshead screws.

- For flush mounting installation, it is recommended to fill the gaps around the embedded box for waterproofing (to prevent water from entering the back cover of the door phone from the gap).
- Or it is recommended to use rain cover.
