The Courbi watertight box (150×110×70mm) is moulded from durable polymer material that is non-corrosive, impact- and pressure-resistant, UV-protected, flame-retardant, and self-extinguishing. Its IP55 rating confirms protection against complete dust ingress and water jets from any direction.

Side caps are specially designed for easy cutting and conduit fitting, and the box is compatible with Racor, Spiral COMBO/DOMO/FORTE, Rigid COMBO/DOMO/FORTE, SiBi, and Courflex cable management systems. Its larger 150×110×70mm body accommodates more wiring connections than smaller IP54 variants.
