FFKu-EL-F-LS0H Low Smoke is a lightweight plastic corrugated pipe made of special plastic, in black (RAL 9005), non-flame-spreading, halogen-free. This plastic corrugated pipe is used in flush-mounted and cavity wall installations. The advantages are the extremely low smoke development. This makes escape routes easier to identify and, because it is halogen-free, no dangerous toxic and corrosive gases are produced. Halogen-free corrugated pipes are marked with a continuous white longitudinal stripe.0605 DIN EN 61386-22 100% halogen-free according to DINV 0604-2-100 Smoke gas density according to DIN EN 61034-2 Minimum compressive strength: 320N/5cm
