FBY-EL-F Highspeed is a lightweight plastic corrugated pipe with a highly slippery inner layer made of polyolefin, non-flame-spreading, in blue. This plastic corrugated pipe is used for flush-mounted, cavity wall and screed installation. The advantage of types 20 and 25 is the highly slippery inner layer. This allows cables and lines to be pulled in over longer distances without any problems. VDE 0605
