Anti-Slip Stair Nosing 35 x 19.5mm Anodised Aluminium, Twin Rubber Inserts

If you are edging stairs that already have their floor covering down and you do not want a heavy, institutional-looking nosing on them, this is the profile that does the job quietly. It is a slim anodised aluminium angle, 35mm across the tread and dropping just 19.5mm down the riser, with two ribbed rubber anti-slip strips set into the walking surface. It screws down through the tread, and because the screws sit in channels underneath the rubber, nothing shows once the strips are pressed back in. Fitters use it on refurbishments where the treads are sound but the front edges have worn, chipped or gone slippery, and on new stairs where the specification asks for a defined edge without a bulky one.

Why it works

Two grip strips, not one

Most trims in this size range carry a single insert down the middle of the tread. This one carries two, side by side, separated by a band of the anodised metal. That matters for the way people actually walk: a foot placed anywhere across the front 35mm of the step lands on rubber rather than on bare metal, and the split between the two strips gives water and grit somewhere to go instead of sitting on one flat rubber face. The strips are ribbed along their length, which is the direction that resists a foot sliding forwards off the nose.

The fixings disappear

The rubber strips are a push-fit into channels in the extrusion, and the screw holes sit inside those channels. You pull the strips out, fix the trim down, then press the strips back in. The finished edge reads as a clean unbroken line of metal and rubber, with no countersunk screw heads catching the light along the step. It also means the strips can be pulled and replaced later if they wear, without disturbing the aluminium.

A shallow profile that sits down

The rear of the tread plate tapers to a thin feather edge, so it lies onto carpet, laminate or vinyl rather than standing proud of it as a trip hazard in its own right. At 19.5mm the front face is about half the depth of the top plate, which keeps the trim visually light on a domestic staircase while still covering the arris of the step.

Where it is used

Office stairs and shared circulation areas, school and college corridors, hotel and restaurant flights, apartment block common stairs, retail units and showrooms, and domestic staircases and loft conversions. It suits medium-traffic internal work. For a school corridor stair taking hundreds of pairs of feet an hour, or for anything outdoors, choose a heavier profile with a published slip rating instead.

Specifications

Choosing the right option

Start with length. Measure the full width of your widest tread and buy the next length up, because the trim is cut to fit on site and a joint mid-step looks poor and collects dirt. A standard UK domestic flight at around 860mm takes the 1.0m; most commercial flights between 900mm and 1200mm take the 2.0m and yield an offcut; the 2.7m is for wide flights, or for buying one length and cutting two narrow treads from it.

Then finish. Silver is the neutral that disappears against grey vinyl and pale laminate. Champagne is a soft warm beige-gold that sits well with oak, beige carpet and cream paintwork. Gold is a brighter brass tone for traditional interiors. All three take the same black insert, so the grip strips read as a dark line whichever carrier you pick.

Installation, use and care

Lay your floor covering first, then offer the trim up so the rear taper sits on top of it and the front leg touches the riser. Cut to length with a mitre saw and a non-ferrous blade, or a hacksaw. Pull both rubber strips out of their channels, mark and drill through the fixing positions, fix down with the supplied screws and plugs, then press the strips back in. Clean with warm water and a neutral detergent. Avoid abrasive pads and solvent cleaners, which dull the anodised surface. If a strip wears, pull it and fit a replacement rather than replacing the whole trim.
