This larger-format circular junction box is built from a non-corrosive, impact- and pressure-resistant polymer with UV protection, flame-retardant and self-extinguishing properties. At 80×40mm it offers more internal cable capacity than the 65×35mm model while still fitting standard surface-mount locations, and it delivers IP 54 protection against dust and water ingress.

Side caps are specially designed for easy cutting and cable or conduit insertion. The box is compatible with Racor, Spiral COMBO – DOMO – FORTE, Rigid COMBO – DOMO – FORTE, SiBi®, and Courflex® wiring accessories, and it meets IEC 60670–1/2002 standards for junction boxes.
