Corrugated electrical conduit 1425_K50D Ø25/18.3 mm is designed for the protection and convenient routing of power, telecommunication, network and signal cables. It is made of durable PVC in light grey and is supplied with an integrated pull wire, which makes cable pulling easier and significantly reduces installation time.

The corrugated 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 25 mm and a minimum inner diameter of 18.3 mm. This size makes it suitable for routing larger-diameter cables or several cable lines, depending on cable dimensions and installation requirements.

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