Premier Double Z TM 4 Double Nap-lock. The solid Brass Top is finished with a selection of coatings and surface treatments seen below. (4mm Gap Between Top And Base Plate).

The Premier Double Z4 uses a base material of solid brass for a high-quality installation. Available lengths: 90cm, 100cm, 180cm and 270cm.

Fitting instructions - The Double Z4 is used for thin carpets i.e. flatweaves/mini boucle sisal products or by peeling off one side (See Image To The Right), it can be used for hard flooring of similar height. Includes 3mm MDF spacer 40cm long. Cut in short lengths and place under nail holes to raise base.

Score along the peel line with a Stanley Knife and peel away with a pair of pliers. The DoubleZ bar will ‘nap’ down if required. Use a block of wood wrapped in carpet and then gently hammer down the trim making it level, never at an angle. Use the MDF strips provided to raise the base 3mm when used in conjunction with an underlay system.
