This simple post base flange anchors vertical square posts to flat mounting surfaces including concrete pads, wood decking, and flooring substrates. The single-plate construction provides a fixed, ground-level base for structural posts used in fencing, pergola frames, garden enclosures, and agricultural settings. Suited for both new post installations and on-site replacement work, this flange establishes a direct, non-adjustable fastening point between the post base and the surface below.
