The Aluminium Square is designed to conceal the edge of a carpet and create a secure join to an adjoining hard floor covering. Suitable for use with a variety of flooring materials, including stone, real wood, ceramic tiles and laminate, it provides a neat and professional finish across doorways and room transitions.
Also known as an SQ profile, this threshold is commonly used where carpet meets another floor covering or where a carpet edge finishes against features such as French doors and door frames.
Manufactured from aluminium, the profile combines a clean square-edge appearance with a durable construction designed for everyday use. It is intended for installations where both floor surfaces are level, allowing the threshold to sit flat across the join.
Available in 900mm and 1800mm lengths, the Aluminium Square can be cut to size on site and is supplied in a choice of nine finishes, including this Brass version.

How to Choose the Right Door Threshold
The Aluminium Square is designed for joining carpet to hard flooring where both floor surfaces are level.
For best results:
- Ensure both floors sit at the same height.
- Measure the doorway or flooring transition before ordering.
- Select a length that can be trimmed to achieve the required fit.
How to Install the Aluminium Square
- Measure the doorway or flooring transition and cut the threshold to the required length using a hacksaw.
- Position the threshold between the carpet and adjoining floor covering.
- Fix the profile using a suitable adhesive, screws or nails.
- Avoid fixing into areas containing underfloor heating.
- Ensure the carpet underlay stops short of the threshold.
- Secure the carpet edge into position.
Once fitted, the threshold can be gently napped down using a carpeted wood block. This can help provide a firmer grip on the carpet and may reduce the finished height by approximately 3mm.
