The pickets on a Radius Picket Fence are 1 1/2" wide and 1" thick with a gently discerned point. The picket spacing of 2 3/8" gives the panel a refined look that changes with the angle of the view. All picket panels are finished off with a kickboard (base moldings) on both the front and back on the bottom. They are attached to posts or columns by screwing through the 1" x 3" nailer at the end of the panel with the provided screws.
