Fastest Available Option*
Premier Slim D Pewter door threshold strips offer a sleek and ultra-discreet solution for joining carpets seamlessly. With a slim 16mm profile and a contemporary pewter finish, this door bar creates a subtle, refined transition that complements modern and classic interiors alike.
Description
The Premier Slim D door threshold is an ultra-narrow double Z bar designed specifically for joining carpet to carpet. Its minimalist 16mm width makes it ideal for achieving a clean, understated finish where a wider door bar would be too prominent.
Finished in a stylish pewter tone, this door threshold strip adds a soft, muted metallic accent that works beautifully with a wide range of carpet colours and interior styles. Unlike standard double Z door bars, the Slim D does not include a built-in base, meaning carpets must be secured using gripper rods beneath for a firm hold.
Perfect for doorways, landings, or across rooms, this door strip provides a neat, professional finish while maintaining a low profile that reduces visible bulk.

How to Choose the Right Size Door Threshold
Start by measuring the width of your doorway or the area where the carpet join will sit. Choose a slightly longer length so the door threshold strip can be trimmed for an exact fit.
As this is a slim 16mm door bar, it is ideal where a subtle, less visible join is preferred. Ensure your carpets are within the recommended thickness range and that both subfloors are level for the best results.
How to Install a Door Threshold Step-by-Step
Installing a Slim D door threshold strip is simple with the right preparation:
Ensure carpet gripper rods are installed on both sides of the join.
Measure the doorway width and cut the door bar to size using a hacksaw.
Position the threshold strip centrally over the join between the carpets.
Tuck the carpet edges neatly into the profile on each side.
Use a carpeted block of wood to gently ‘nap down’ the threshold, pressing it into place.
Ensure the bar sits flush and secure to avoid movement or gaps.
To remove an existing door threshold, start by identifying how it has been fixed in place. Most door thresholds are secured using either screws, nails, or adhesive.
If the threshold is fixed with screws, use the correct screwdriver to carefully remove them. If the screws are difficult to turn or stuck in place, gently tap the screw heads with a hammer to help loosen them before attempting to unscrew again.
For thresholds secured with nails, use a claw hammer or pry bar to carefully lift and remove them. Work slowly and evenly along the length of the door bar to avoid damaging the surrounding flooring.
If the door threshold strip has been fitted tightly into carpet (as with double Z bars), gently lift and release the carpet edges first before removing the bar. Take care not to damage the carpet fibres or underlay.
Remove any remaining fixings or debris to prepare the area for your new door threshold strip.
Cleaning & Maintenance
Vacuum regularly to prevent dirt build-up around the door strip
Wipe with a soft cloth and mild cleaner when needed
Dry thoroughly after cleaning
Avoid abrasive cleaning products
Use a suitable metal polish if you wish to maintain the original finish
