We can offer replacement panels upon request only. We can only offer panels for the new quad-rail track, but not the double-rail track since this item has been discontinued. The panels for the new track are also larger than the panels for the older unit and come in a different selection of colors and fabrics.
The panels are sold in packs of two panels for $40 each. A full set of replacement panels for one track would cost $80 total. We do recommend requesting some sample swatches to see the materials in person before placing an order.
Please reach out to our support team at email@example.com if you have any questions or if you would like to receive sample swatches.
