Schneider Electric IMT80278 is a Multifix round wall-mount device box for single-module devices, designed for casting into concrete with 32 mm inlet spacing. It ships with a pouring cover and integrated nail-fixing lugs so the box can be positioned before concrete is placed. Six break-out inlets accept 16/20 mm installation conduit for termination flexibility, and a rotating carrier ring allows the finished device to be levelled on site. Typical use is in Nordic residential and commercial construction where switches and sockets are cast flush into concrete walls.
