The protective roof protects the AMTRON® Wallbox from expensive damage: Vandalism, weather damage or other damage is prevented and the charging station is protected as best as possible. We generally recommend purchasing the protective roof when purchasing any MENNEKES AMTRON® Wallbox. Such a protective roof offers optimal protection for the Wallbox, especially when using the charging station in (semi-)public areas where the likelihood of potential damage tends to be higher than in home use.
