The door threshold bars – Premier Single 9 with a rounded profile
Choose from ten attractive metal finishes
The door threshold bars – Premier Single 9 are an elegant and secure way to join a carpet to a thinner floorcovering, such as vinyl, LVT, Amtico or bare floorboards.
This design of door bar features a smooth, curved edge which slopes down from the carpet pile to the vinyl or floor boards.
The two base floors should be level with each other as the Single 9 needs to lie flat (see diagram). However, if yours are slightly different, stack the MDF strips (also known as Easywedges and included free of charge) underneath the Single 9 and raise/tilt the base.
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 9 is suitable for most qualities of carpet which compress to around 9mm thick. The underlay is cut short of the door bar. If your carpet is thinner please see the Single 4 or if thicker try the Premier Single 13
Made with a solid brass bar, with rounded edges, in a choice of 10 smart, natural metal finishes.
Available 900mm, 1000mm, 1800mm and 2700mm.
Also known as Premier Trim Single or a Single Naplock.
Fitting tips for door threshold bars – Premier Single 9
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.
Thick carpets can be compressed onto the pins before napping down (see above).
Once fitted, Premier Door Bars Single 9 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 by 3mm.

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. Please see our How to Guide: Cleaning Door Thresholds
These Premier Single 9 door thresholds are top quality, made from really good materials and are superior to any products you can buy in carpet/diy shops. They are considerably more expensive but quality comes at a price. Would most certainly recommend these door thresholds.

Have you ever thought a product you chose on a website doesn’t look the same colour in reality? A prime reason is that computer and mobile screens, operating systems and even web browsers have different colour characteristics, this therefore affects the colours you see on your screen(s). We therefore cannot guarantee that your screen accurately reflects that of the products.
