On offer here is the premium quality trellis backing rail that is needed to construct your own trellis fencing. Without the backing rail you have no place for the trellis to be positioned & therefore no fencing. The backing rail is manufactured from a top slow grown soft wood which has been pressure treated also. The extra time that the timber is given to mature increases the toughness of the timber & therefore means your fence is much more stable. Furthermore, the pressure treatment creates a defensive layer that will protect your fence from rot & other weathering damage. Fitting the backing rail is very simple & once attached to poles, will secure an area for your animals/pets for time to come. For use with trellis Pressure treated timber 15 year anti-rot guarantee
