Product Overview
This rake back aluminium stair nosing is built for staircases where the riser face angles back beneath the tread — a common configuration in both new-build and refurbishment projects. The double channel layout accommodates two parallel PVC insert strips, increasing the slip-resistant surface area at the step edge and allowing dual-colour or hazard-highlight configurations where enhanced visibility is required. At 85mm across the tread and with a 3.5mm gauge profile, it offers a robust yet low-profile finish that sits flush with the surrounding floor covering without creating a trip hazard of its own. The 3.22m stock length makes it practical for a wide range of stair widths, with straightforward on-site cutting using standard metal-cutting equipment.

Frequently Asked Questions
What is a rake back stair nosing and how does it differ from a standard nosing?
A rake back nosing has an angled riser face that follows the slope of the riser beneath the tread, rather than a straight vertical drop. This makes it the correct choice where the stair riser angles back under the step, ensuring a flush, secure fit against both the tread and riser surfaces.
Can this nosing be cut to fit narrower or wider stairs?
Yes. The 3.22m (3220mm) stock length is designed to be cut on site to the exact width of each stair tread. A standard metal-cutting saw or mitre saw with a fine-tooth blade is suitable. Always deburr cut ends before installation.
What does double channel mean and why does it matter?
Double channel means the aluminium profile contains two parallel grooves, each accepting a PVC insert strip. This doubles the slip-resistant surface area at the step edge compared to a single channel profile, and also allows two different insert colours to be used — for example, combining a neutral tone with a Hazard insert for improved visibility.
Which floor coverings is this nosing compatible with?
This profile is designed for use with vinyl, lino and lightweight carpet floor coverings on internal staircases. The rake back profile and 3.5mm gauge are specifically suited to the thinner floor covering depths typical of these materials.
