All pen section are made of 2x2” timbers for the uprights and a 4x1” top rail with a standard 2X 6x1” for the bottom, the wire I recommend for partridge rearing is the 19mm hole 19m gauge wire as this the thickest and strongest wire on the market suitable for the job and with a small saving you can have 25mm hole with 19mm gauge.
These sections are built to last and won’t let you down on high tension roof nets.
