Corrugated Conduit with Pull Wire Ø20/14.1 mm, PVC, 50 m, Light Grey KOPOS 1420_K50D

KOPOS 1420_K50D corrugated electrical conduit is designed for the protection and routing of electrical, network, telecommunication, signal and other low-voltage cables. It is made of PVC in light grey and is supplied with a pull wire, which simplifies cable installation inside the conduit and reduces installation time.

The conduit is suitable for both surface-mounted and concealed installations. It can be installed on surfaces, in screed, under plaster, inside hollow and plastered walls, as well as in ceiling structures.

The conduit has an outer diameter of 20 mm and a minimum inner diameter of 14.1 mm. Mechanical resistance of 320 N/5 cm provides additional protection for installed cables against mechanical loads during installation and subsequent operation.

The operating temperature range is -5 to +60 °C, while the self-extinguishing time of the material is 30 seconds.
