Crop Bar Kit for 14ft x 20ft Polytunnel (@ 5ft)
The crop/tie bars on our 14ft wide polytunnels are made from 38.1mm diameter high strength galvanised tube with inverted V-hangers, from diameter 25mm tubing, to the ridge tube. This results in a strong truss arrangement which is far stronger than a simple horizontal bar. The crop/tie bars on our 14ft wide polytunnels will also increase the wind and snow load capacity of the 'tunnel by about 20%.
