SCHNEIDER ELECTRIC APPARATUS BOX MULTIFIX 1M 12-27 MM 2 RIGID STUBS

Installing switches and sockets into hollow walls often means struggling with flimsy boxes that shift, crack, or fail to grip the plasterboard. The Schneider Electric Multifix cavity wall box solves this by providing a rock-solid, adjustable mounting platform that locks securely into walls from 12 to 27 mm thick. Its two rigid stubs offer clean, protected cable entry, while the halogen-free polypropylene body meets strict safety standards for modern electrical installations.

Tips

Before cutting the hole, always check the exact wall thickness to ensure it falls within the 12–27 mm range. For a clean finish, use a hole saw slightly larger than the box diameter and deburr the edges. When routing cables through the rigid stubs, strip only the necessary outer sheath to maintain strain relief. For multiple boxes side by side, use the manufacturer's coupling pieces to maintain consistent spacing and alignment.
