This 4' high Kennedy fence uses 2" x 2" Sawtooth (pointed top) pickets set at an even height. The pickets are sandwiched by (2) - 1" x 4" routed top rails and (2) - 1" x 6" routed bottom rails. The top rails are routed on the top and bottom while the bottom rails are routed only on the top. The pickets here are spaced 2" apart. 6" x 6" posts with 6" Ball Tops atop 2" x 7.5" plates.
