The BN9 Brass Stair Nosing is a premium solid brass stair edging manufactured from high-quality CZ108 grade brass, designed to deliver exceptional durability and a refined finish in both commercial and residential environments.

Featuring a serrated slip-resistant tread and a square riser profile, this low profile stair nosing enhances safety underfoot while maintaining a clean, modern aesthetic. Its 2.2mm gauge construction ensures long-lasting performance in heavy foot traffic areas such as hotels, offices, schools, retail spaces and apartment buildings.

The BN9 is specifically designed to butt seamlessly against vinyl and LVT flooring including popular brands such as Amtico and Polyflor, making it an ideal solution for contemporary flooring installations. It can also be rebated into timber stairs for a flush finish, providing flexibility across a range of applications.

Available in CAT’s four signature brass finishes, this stair nosing can be supplied drilled or undrilled to suit your installation requirements. Each profile is cut to size (up to 2700mm) for precise fitting and professional results.

With excellent slip resistance values (SRV Wet: 45 / Dry: 73) and full recyclability, the BN9 offers a perfect balance of safety, performance and sustainability.

Dimensions may vary by up to ±5mm in line with supplier manufacturing tolerances.
