STEFFEN Installation conduit corrugated M25 10m blue – Flexible cable protection with draw wire
The STEFFEN installation conduit is a corrugated plastic protective tube in blue, designed for routing electrical cables in buildings. The corrugation provides high flexibility, allowing it to be guided around tight radii.
The conduit includes an integrated draw wire that simplifies cable installation and replacement, saving time on every job.
The flame-retardant version (KRFWG) offers enhanced fire safety, particularly in sensitive building areas.
With a width of 25 mm and a length of 10 metres, it covers typical installation routes without needing many joints.
The blue colour serves as identification for data or low-voltage cables, making it easier to distinguish on the construction site.
What sets the STEFFEN installation conduit apart
Unlike rigid pipes or simple corrugated conduits, this model combines flexibility, fire protection and a practical draw wire. The KRFWG classification (class B2 according to DIN 4102) makes it suitable for both public buildings and residential use.
Ideal for...
This conduit is ideal for electricians and DIY enthusiasts who want to safely route cables in drywalls, concrete slabs or cavities. For subsequent wiring in already finished walls, the combination of flexibility and draw wire is optimal.
How to use the installation conduit
1. Determine the required cable length and cut the conduit to size using suitable shears or a cutter. 2. Pull the cables through using the draw wire. 3. Fix the conduit with clips or cable ties to the substructure. 4. Connect the cables to the desired sockets or devices and check continuity.
