The NSL21 Aluminium Stair Nosing is a robust, DDA-compliant stair edge profile engineered to improve safety, visibility, and accessibility in both commercial and public environments. Featuring a straight edge, ramped tread, and a single anti-slip insert channel, this profile delivers secure footing and a sleek finish on various step types.

Crafted from durable aluminium, the NSL21 is designed to endure heavy foot traffic, with strong resistance to wear, corrosion, and impact. The ramped tread ensures smoother step transitions, reducing trip risks, while the contrasting insert enhances visual definition—supporting compliance with the Disability Discrimination Act (DDA) and BS8300:2009+A1:2010.

Ideal for installation with vinyl, LVT, laminate, and other resilient floor finishes, the NSL21 is suited for a wide range of projects, from schools and offices to retail spaces, shared stairwells, and public buildings.

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.
