FFKu-EM-F-LS0H Low Smoke is a medium duty corrugated special plastic conduit, in black (RAL 9005), zero halogen, non-flame propagating.
This corrugated plastic conduit is used in concrete and cavity wall installations.

An advantage is that very little smoke gas is generated. Escape routes can be found more quickly. Since there is zero halogen, no dangerous toxic and corrosive gases are produced.

Zero halogen corrugated conduits are marked with a white stripe.
