Aluminium Double Z - Brass

• The carpet to carpet threshold Ali Double Z is an elegant and secure way to join a carpet to another carpet in a doorway. Unlike carpet door bars you can buy at the DIY shops, these are made to last, will not easily scuff or dent and will look the part for years to come.
• Likewise suited to joining a carpet to a hard floorcovering by removing one base section - see the Premier Z9 for more information..
• The Double Z9 are designed to take a quality carpet up to around 12mm thick or pile height (excluding the underlay).
• The two floors should be level with each other for the Double Z (otherwise known as ZZ9 or double naplocks) to lie flat. However, if yours are slightly different, stack 3mm thick MDF strips, underneath.
• If one of your carpets needs to be raised up to the level of the pins, buy the Easyshims to create a ramp.
  
• Available in 2 alternative lengths which are suitable for cutting to length: 900mm & 1800mm.

Width options

• The visible bar or top of these Double Naplocks is 30mm (just over 1") wide and approximately 4mm thick.

• Cut to length with a sharp hack-saw.
• Stick, using a propriety adhesive, nail or screw (avoiding any underfloor heating).
• For images and information on how to convert the Double Z so as to be able to join a hard floor, such as ceramic tiles or wood, to a carpet, please see the Premier Z.
• Note: any underlay stops short of the door threshold.
• Once fitted, the Double Z 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.
