Kentucky Board Fence, also called horse fence, board fence, plank fence, and post and rail fence, comes in a variety of styles and designs along with several post combinations, from 4x4’s, 6x6’s to round and round faced posts. Kentucky board fences are seen throughout the rolling hills, pastures, and residential back yards in the greater Cincinnati and tri-state area and are also one of the most affordable options. Three rail and four rail are the most common styles seen today.
