FAQ

Q: Is NSL21 suitable for outdoor staircases and high-footfall areas?
A: Yes. The anodised aluminium body and UV-stable PVC insert are suitable for most outdoor and high-traffic environments. For extremely corrosive settings (e.g., coastal or chemical exposure) request a specialist finish or consult the supplier for marine-grade options.
