This circular junction box is built from a non-corrosive, impact- and pressure-resistant polymer with UV protection, flame-retardant and self-extinguishing properties. At 65×35mm it is compact enough for surface-mount runs while providing IP 54-rated protection against dust and water ingress.

Side caps are specially designed for easy cutting and cable or conduit insertion, and the box is compatible with a wide range of Courbi wiring system accessories including Racor, Spiral COMBO – DOMO – FORTE, Rigid COMBO – DOMO – FORTE, SiBi®, and Courflex®. It meets IEC 60670–1/2002 junction-box standards.
