KOPOS 1420_F50D corrugated electrical conduit Ø20/14.1 mm is designed for the protection and routing of electrical, telecommunication, network, signal and other low-voltage cables. It is made of durable PVC in black and features UV resistance, making it suitable for installations where the cable route may be exposed to sunlight.

The conduit has an outer diameter of 20 mm and an inner diameter of 14.1 mm. The integrated pull wire significantly simplifies cable installation inside the conduit and reduces installation time.

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

Mechanical resistance of 320 N/5 cm provides additional protection for the cable route against mechanical loads during installation and subsequent operation.
