FBY-EL-F Highspeed is a lightweight plastic corrugated pipe with a highly slippery inner layer made of polyolefin, non-flame propagating, in blue. This plastic corrugated pipe is used for concealed plaster, cavity wall and screed installation. The advantage lies in the highly slippery inner layer in types 20 and 25. This allows cables and lines to be pulled over longer distances without any problems. VDE 0605, DIN EN 61386-22, minimum compressive strength: 320 N/5 cm
