The Unix Metal Gang Box is the foundation of a safe and professional electrical installation. Crafted from high-quality galvanized steel, this 3-module box is built to be embedded within masonry walls. It features a robust earthing point to ensure maximum safety against electrical faults. The undercut configuration provides extra depth and room for complex wiring and terminal connections. Designed with precisely aligned screw holes, it makes the final installation of modular plates fast and accurate. The corrosion-resistant coating protects the box from moisture typically found in new construction. This is the professional's choice for a reliable, permanent modular switching base.
