The AR6 DHC Aluminium Ramp Threshold is designed to create a smooth transition between adjoining floor coverings installed at different heights while protecting exposed floor edges from impact and wear.

Manufactured from durable 6063 T6 aluminium, the profile features a 38mm visible surface width and accommodates floor height differences of up to 6mm. The ramped design reduces trip hazards while delivering a clean, professional finish.

This version is supplied pre-drilled for mechanical fixing and is designed for installation using size 6 screws. Mechanical fixing provides a secure, long-lasting installation, making it ideal for demanding commercial and public environments.

Part of the premium Designer Home Collection (DHC), the AR6 DHC is available in eight decorative finishes. Matching screws are available in Bright and Designer Satin finishes. Suitable for hotels, offices, retail spaces, schools, public buildings and quality domestic projects.

Available in 900mm and 2715mm lengths. Manufactured from fully recyclable aluminium with a 6mm internal height and 38mm visible surface width.

Dimensions may vary by up to ±5mm in line with supplier manufacturing tolerances.

Installation

  1. Ensure the subfloor is clean, dry and structurally sound.
  2. Position the profile in its final location and use the pre-drilled fixing holes as a guide to mark the substrate.
  3. Remove the profile and drill the marked positions using a suitable drill bit for the substrate.
  4. Insert appropriate wall plugs where required.
  5. Position the profile and secure using suitable No. 6 countersunk screws. Do not overtighten.
  6. Where fitting carpet, trim the carpet edge neatly and tuck it into the naplock section, ensuring the gripper securely retains the carpet.
  7. Check that the profile is firmly fixed and sits level against both floor coverings.

Profiles are supplied with a protective film applied to the visible surface. Leave this in place until all installation work has been completed.
