The Premier Single 4 curves down to join thin carpets and natural flooring to vinyl and floorboards
Choose from ten stunning finishes
- The Premier Single 4 door thresholds are a smart way to join a stick-down carpet and natural sisal up to 4mm thick to floorboards and thin vinyl flooring.
- Features a smooth, curved edge to create a smooth transition and avoid a trip hazard - see diagram for further details.
- The two floors should be level with each other as the Single 4 needs to lie flat.
- The carpet is gripped under tension by the teeth, whilst on the other side the floorcovering lies under the curved edge. This means no raw edges or rucked up carpet.
- The Single 4 is suitable for thin carpet/stick-down carpet only. Any underlay is cut short of the door bar.
- Made with a solid brass bar, with rounded edges, in a choice of 10 smart, unlacquered, metal finishes.
- Available 900mm, 1000mm, 1800mm and 2700mm.
- Also known as Premier Trim Single or a Single Naplock.
- If your carpet is standard thickness, select the Premier Single 9 carpet threshold instead.
Fitting of the Premier Single 4 door thresholds
- Cut to length with a sharp hack-saw.
- Stick, using a propriety adhesive, nail or screw (avoiding any underfloor heating).
- The underlay stops short of the door threshold.
- Once fitted, Premier Door Bars Single 4 can be 'napped down' with a carpeted wood block, which will give the carpet an extra firm grip on the pins and can reduce the height further.

Looking after & cleaning door thresholds
This product is made of solid brass and hand-finished and therefore the finish may vary slightly from batch to batch. To achieve an authentic look and withstand daily use, they are unlacquered and therefore may age naturally over time, depending on their environment.
