The Premier Slim Z Black door threshold is a sleek, minimalist solution for joining carpet to hard flooring where a clean, unobtrusive finish is essential. With an ultra-slim 22mm width, this low-profile Z bar is designed for modern interiors, narrow door frames and open-plan spaces where wider thresholds would feel visually heavy.
Finished in matte black and manufactured from solid brass, the Slim Z combines contemporary styling with dependable performance, securing carpet edges neatly against fixed hard floors.
A Slimmer Approach to Floor Transitions
Unlike standard Z bars, the Premier Slim Z is deliberately narrow, making it ideal where subtle detailing matters. At just 22mm wide, it offers a refined alternative to wider profiles while still performing the same essential function: holding carpet firmly in place and providing a tidy join to hard flooring.
This makes it particularly well-suited to:
- Modern and minimalist interiors
- Doorways with shallow frames
- Open-plan layouts where transitions should remain discreet
How the Premier Slim Z Door Threshold Works
The Slim Z features a visible top bar with a concealed base section beneath one side. This base grips the carpet securely, while the vertical section is designed to be gently pressed down into the carpet pile during fitting.
Once installed, the bar sits neatly within the carpet rather than standing proud, creating a flatter profile and a more integrated finish.
Flooring Suitability & Height Requirements
The Premier Slim Z Black can be used for:
- Joining carpet to a hard floor such as wood, tile or stone
- The hard flooring is securely fixed
- There is minimal or no expansion movement in the hard floor
The two floor surfaces should be level with each other. The Slim Z lies flat on the sub-floor and fits over the top of the hard floor covering.
If the hard floor sits slightly higher than the carpet, you can use the supplied 3mm MDF packing strips beneath the base section to raise the bar accordingly. If the carpet is significantly lower, Easyshims may be required.
If your hard floor needs expansion space, this product is not suitable; a standard Z bar should be used instead.

Installation Overview & Fitting Tips
The Slim Z is suitable for DIY installation, though careful fitting is important to achieve a clean result.
Recommended tools:
- Tape measure
- Pencil
- Drill and screwdriver
- Sharp hacksaw
- Hammer and wooden block
Key fitting advice:
- Only use on hard floors with minimal movement
- Cut the bar to length before fixing
- Place MDF strips at fixing points if height adjustment is needed
- Nail MDF strips securely to the sub-floor
- Once the carpet and underlay (if used) are in place:
- Place a block of wood wrapped in carpet on top of the bar
- Gently tap with a hammer to depress the bar by approximately 3mm
This process helps the pins grip the carpet more firmly and lowers the overall profile.

Will the black finish suit modern interiors?
