47mm Self-Adhesive Aluminium Threshold Strip

47mm Self-Adhesive Aluminium Door Threshold Strip – 930mm

5-in-1 Transition Profile with Self-Adhesive and Concealed Dowel Fixing

Create a clean and durable connection between adjoining floors with our 47mm Self-Adhesive Aluminium Door Threshold Strip. Designed for internal doorways and room transitions, the profile covers flooring joins while protecting exposed edges from everyday wear.

The threshold is suitable for fitted carpet, parquet, laminate, vinyl, tile and terracotta flooring. Its 47mm width provides generous coverage over expansion gaps and can help manage minor differences between adjoining floor levels.

Manufactured from durable anodised aluminium, the profile offers good resistance to corrosion, regular foot traffic and everyday use. It is available in a wide choice of anodised, brushed and polished finishes to complement both modern and traditional interiors.

The versatile 5-in-1 installation system provides two main fitting options: self-adhesive installation or concealed dowel fixing. Both methods leave the upper surface free from visible screw heads, creating a neat and professional finish.

Benefits of This Aluminium Threshold Strip

Choice of Two Fitting Methods

Use the self-adhesive backing for quick installation or choose concealed dowel fixing where a mechanical connection to the floor base is preferred.

Clean Invisible Mounting

The dowels and adhesive remain beneath the profile, leaving the visible aluminium surface free from exposed screws and fixing holes.

Covers Wider Flooring Joins

The 47mm profile offers useful coverage over expansion gaps, cut floor edges and transitions between different flooring materials.

Helps Manage Minor Level Changes

Its transition shape can create a smoother connection between floors with small differences in height.

Choice of Finishes

Anodised, brushed and polished colour options make it easier to coordinate the threshold with flooring, doors and other interior fittings.

Installation Guide

Self-Adhesive Installation

1. Measure the doorway and flooring join carefully.
2. Cut the aluminium profile to the required length using a fine-tooth hacksaw.
3. Smooth the cut edge with a suitable metal file.
4. Position the strip over the join to check its alignment and coverage.
5. Clean and degrease the installation surface thoroughly.
6. Remove all dust, moisture and loose material.
7. Allow the surface to dry completely.
8. Peel away a small section of the protective adhesive backing.
9. Align the threshold carefully over the flooring join.
10. Remove the remaining backing gradually while pressing firmly along the full length.
11. Allow the adhesive sufficient time to bond before subjecting the profile to heavy foot traffic.

Concealed Dowel Installation

1. Measure, cut and position the threshold over the flooring transition.
2. Mark the required fixing locations.
3. Check for hidden pipes, electrical cables and underfloor heating before drilling.
4. Drill suitable holes into the floor base.
5. Insert the supplied plugs into the prepared holes.
6. Slide the concealed fixing dowels into the track beneath the profile.
7. Align the dowels with the drilled holes and plugs.
8. Press the threshold down evenly until all fixings are securely seated.
9. Check that the profile covers both flooring edges and remains stable along its full length.

For self-adhesive fitting, install the strip only on a smooth, solid, clean and dry surface. Do not attach the adhesive directly to loose carpet fibres.
