The Redwood Fence board is untreated, redwood is a natural and eco-friendly option.
Most standard fence dogear fence are 6' length. 8' footers my view you will need additional cross member supports cut pieces at 2 feet, with custom facia board to hide split cut. As the 2 foot pieces would be attached at the bottom of fence. Good luck.
building a common wood fence that is 265 liner feet with existing metal poles, two man gates and one gate 8' for vehicle how much would total price be for all material
Pickets are 5.5 inches wide so 5.5 X 400 = 2200 inches divide by 12 to get feet 183 feet.
