WALL

WALL is the smart, modular mailbox system for apartment buildings and commercial properties. You configure it in the size you need and choose either the digital version with connectivity or a budget-friendly model without cabling.

Modular and smart

WALL is built from robust aluminium modules that can be used both indoors and outdoors. This allows the system to scale with the number of residential units while maintaining a sleek, continuous surface in the entrance hall.

WALL Digital

The digital variant offers connectivity via an app and a management portal, with smart access via PIN code, RFID or smartphone and integration with video intercom and keypad. You can discuss the exact configuration with ONZO.

For new builds and renovations

WALL fits both in a new build project and when replacing an outdated installation. Request a custom proposal via the project scan.
