To use the Berker 91820, first ensure the wall cavity is prepared to the correct depth and dimensions. Insert the box into the wall opening and secure it firmly using appropriate mounting hardware. Once the box is stable, route the electrical cables through the designated entry points before connecting your switches or sockets.

Usage recommendations: For optimal results, always use professional tools to cut the wall opening to the exact size required. Ensure that all cables are properly stripped and secured within the box to prevent strain on the terminals. If installing in masonry, use appropriate mortar or fixing materials to ensure the box remains immovable over time.
