2096-3	perimeter, breeding & fawning pens, high pressure areas	tighter 3″ spacing for greater strength & smaller animal control
2096-6	boundary fence, medium-to-high pressure	strong, cost-saving 6″ spacing
2096-12	internal fence, low pressure situations	12″ spacing for economy
1775-6	internal fence for smaller deer species	lower fences saves on materials costs-deciding factor is jump height of species in question
