The NSL21 Aluminium Stair Nosing with Tredsafe® insert is a high-performance, DDA-compliant stair profile designed to improve step-edge visibility, slip resistance, and regulatory compliance in public and commercial buildings.

Featuring a ramped tread and straight edge, the NSL21 ensures smooth foot transition while delivering a clean, architectural finish. Its robust aluminium construction is ideal for high-traffic environments like schools, offices, transport hubs, and multi-residential buildings.

The integrated Tredsafe® anti-slip insert, made from a durable blend of PVC, silica quartz, and polymeric plasticiser, provides exceptional grip via a 3D pyramid-textured surface, offering safety in both wet and dry conditions. The profile is fully compliant with BS8300:2009+A1:2010 and Approved Document M, making it ideal for accessible design specifications.

Supplied pre-drilled through the insert, with colour-matched pips to conceal fixings. Undrilled and channel-only configurations with separately supplied inserts are available upon request. Fixings not included.
