The Courbi Super Switch Box is a round recessed junction box intended for flush-mounting switches and sockets in masonry walls. Moulded from a special polymer material, it is non-corrosive, impact and pressure resistant, flame retardant, and self-extinguishing — properties that make it appropriate for both residential and industrial indoor electrical installations.

The Φ65×38mm body suits all standard Courbi conduit systems including Spiral COMBO, DOMO, FORTE, and COMBO Rigid L/T. It accepts single-frame switch and socket combinations, enabling multiple configurations to be connected within one box opening.
