Silent Gliss Double Track – 6840 / 6840 Curtain Track System

With 60mm Wave Gliders

Silent Gliss 6840 curtain track systems sold as a complete twin track system for either wall or ceiling fixing.  Both 6840 tracks are supplied with 60mm wave gliders.  The double track system  wall fixed isn’t suitable for 80mm wave gliders as the depth of the wave is too big to fit without the curtains rubbing each other.

  • Ceiling fixing uses the standard ceiling fix brackets for each track.  Each track is fitted independently.
  • Wall fixing uses the Universal Smart Fix bracket system – the ceiling fix brackets from each track fit to the extension arms on the Universal Smart Fix brackets.  Both tracks are suspended from the Universal Smart Fix brackets.
  • 3-4 working day lead-time. This track comes complete with gliders, brackets and fixings.

Whilst we will endeavour to fulfil our delivery promises once the goods leave our warehouse we do rely on 3rd parties to fulfil their obligations.  We therefore recommend that a fitter isn’t booked until the goods are safely in your hands and have been checked for damage and any missing items.  We cannot be held responsible for any fitter cancellations.

We hope that you are delighted with your purchase.  We do recommend paint sample pots, wallpaper and fabric swatches are ordered prior to ordering the full sized items.  We can also send out ring samples, colour toggles or off cuts of curtain poles / tracks to ensure the colour is right before you commit to order.  Please email to request a sample.  Please note made to order / measure / cut to size products cannot be returned or exchanged unless faulty.  Please also note that we cannot accept returns on any paint orders as they are mixed to order.

For any standard products not listed above, in the event that you would like to return your goods we accept returns within 30 days of delivery.

There is an £20 collection charge to return curtain pole or curtain track orders. We appreciate this is a lot of money but this is what our couriers charge us. Curtain poles and tracks are classified as ‘oversized’ items and so they incur a premium for handling long parcels.

If you would like to return curtain pole accessories or curtain track spare parts these can be returned by Royal Mail or a carrier of your choice.  Please return smaller items to: The Home Of Interiors, 19 Brookley Road, Brockenhurst, Hampshire, SO42 7RR.

To return and obtain a refund (excluding delivery costs) please email us at or give us a call us on 01590 615775. We will then contact you to organise the collection / return. Failure to notify us may result in no refund or an additional cost to forward your returned item/s to the correct address.

Any products you return will be at your own cost and the goods must be in the same condition which they were received.  The goods must be in their original packaging.  The goods are your responsibility until they reach us so please make sure any returned items are very well packaged to avoid damage while in transit. Please ensure the returns reference, which will have been emailed to you, is clearly marked on the outside of the parcel.  We recommend you use the outer packaging the goods were delivered in.

If on receipt of the goods we inspect them and conclude that they are not in the same condition they were sent out in we will not be able to provide a refund. We will notify you if this is the case.

The refund, minus the original delivery charge and minus the collection charge, is usually actioned within a week of the items being returned but it can take up to 30 days. The refund will be made back to the account that the original purchase was made from.
