Product Features
- Rake back double channel profile — designed to sit flush against the riser face for a clean, integrated finish on standard stair constructions.
- 3.5mm gauge aluminium alloy body provides a robust, impact-resistant step edge that withstands sustained high footfall without deforming.
- Double channel configuration securely retains two rows of exterior grip PVC insert, maximising the slip-resistant tread area across the full 85mm nosing width.
- Exterior grip inserts deliver enhanced traction underfoot, making this profile well suited to environments where moisture, dust, or heavy use increase slip risk.
- Replaceable PVC inserts allow worn sections to be renewed independently, extending the service life of the aluminium profile and reducing long-term maintenance costs.
- Six architectural aluminium finishes — Bright Polished, Dark Bronze, Mill Finish, Mirrorflect Gold, Satin Black, and Satin Gold — to complement a wide range of interior and exterior design schemes.
- Three exterior grip insert colours — Brimstone, Coal, and Everest — provide clear visual contrast at the step edge to aid safe navigation in varied lighting conditions.
- Supplied in three stock lengths (2.44 m, 2.75 m, and 3.22 m) to suit standard stair widths; profiles can be cut to the required length on site.
- Pre-drilled countersunk fixing holes allow straightforward screw-fixed installation directly to the stair tread substrate.
- Compatible with vinyl, lino, and lightweight carpet floor finishes, making it a versatile choice for refurbishment and new-build projects alike.

Frequently Asked Questions
What is the difference between an exterior grip insert and a standard PVC insert?
An exterior grip insert is formulated from a harder-wearing PVC compound with a more aggressive surface texture, providing greater traction underfoot. It is designed for environments subject to heavier use, moisture, or covered outdoor exposure, whereas a standard PVC insert is suited to typical internal conditions.
What does “rake back” mean and how does it affect installation?
A rake back profile has an angled rear face that sits flush against the vertical riser of the stair, rather than sitting flat on the tread alone. This gives a neater, more integrated appearance and is the correct profile for standard stair constructions where the nosing meets the riser face directly.
Can the stock lengths be cut down to fit a narrower staircase?
Yes. All three stock lengths — 2.44 m, 2.75 m, and 3.22 m — can be cut to the required width on site using a standard aluminium-rated mitre saw or hacksaw. The PVC inserts can be trimmed to match using a sharp utility knife.
Is this nosing suitable for outdoor use?
This profile is suitable for covered external stairways where it is protected from direct rainfall and prolonged standing water. The exterior grip inserts are specifically selected for more demanding environments. It is not recommended for fully exposed outdoor steps subject to direct weathering.
