The Courbi Sibi Wire is a corrugated (spiral) semi-flexible conduit made from polyvinyl chloride — pipe body in U-PVC and inner lining in P-PVC. It is designed for electrical installations in concrete boxes, indoor runs, and garden applications where medium mechanical protection is required. A built-in galvanised steel-wire cable guide (ατσαλίνα) runs inside the conduit for quick and easy cable installation.

Classified under EN 61386-1/2004 and EN 61386-22/2004, and dimensioned to DIN 49018. The conduit is self-extinguishing and does not transmit flame. It is available with a special socket for quick connection to junction boxes and SPOT fittings. Priced per metre; sold in 25m packs.
