This professional-quality 40mm Aluminium Door Threshold is a highly versatile transition profile designed to accommodate different floor heights and uneven levels.
The adjustable system allows the threshold to raise, lower, or tilt as required, making it ideal for joining floor surfaces with height variations.

Supplied with both small and large clips, it can be modified to suit a wide range of floor coverings, providing a clean, seamless finish between carpet, wood, laminate, tile, vinyl, and LVT flooring.

These durable aluminium profiles are easy to cut to size using a hacksaw and can be secured to wood or concrete subfloors using nails or screws.
Perfect for domestic and commercial installations requiring a neat, safe, adjustable floor transition.

Please refer to the technical drawings for supported height-adjustment options.

Installation Instructions

1. Ensure the threshold cover is wide enough to bridge the gap between your two floor coverings.
2. Fit the aluminium base rail, securing it with contact adhesive or mechanical fixings (screws/nails).
3. Slide the appropriate clips (small or large) onto the cover — place 2–3 cm from each end and space the rest evenly.
4. Align the clips with the base, apply even downward pressure, and lock them into place.
5. Use a rubber mallet if necessary to achieve a tight, secure fit.

Installation Tip (Highly Useful)

If the clips feel difficult to push in:
Insert a red clip upside down, gently tap with a mallet, then remove it.
This widens the slot slightly, making the threshold and clips slide into position more easily.
