The ASL25 69 x 40mm Slimline Ramped Bullnose Tredsafe Stair Nosing is a stylish and functional stair edging solution, designed to provide safe step definition and a smoother transition between flooring finishes. Its ramped design and bullnose front edge deliver a clean, professional finish while enhancing underfoot safety in both commercial and domestic environments.

Part of the Tredsafe Aluminator® range, this profile features a glow-in-the-dark photoluminescent insert that charges under daylight or artificial lighting. In low-light or power-outage situations, the insert illuminates automatically—helping guide foot traffic and improving stair visibility without the need for wiring or maintenance.

Built from high-quality aluminium and fitted with a durable non-slip PVC insert, the ASL25 is ideal for internal and external stair installations across a wide variety of substrates, including concrete, tile, timber, vinyl, steel, and checker plate. Supplied pre-drilled through the insert for easy installation, with matching insert pips included. Undrilled and custom channel options with separate inserts are available on request.
