Why is the netting longer than the pole of the Chicken Fencing?

Due to the way these nets are made and trimmed, the factory is unable to achieve consistent results every time and across all batches. The nets are not made in static moulds, like the rigid panels of our chicken houses, but are made using a kinetic process with inherently larger dimensional tolerances. These nets will often have some variation in height or around 50mm and may have 24 or 25 mesh squares.
