3 1/2 x 48 Notched Newel Post. Ascension Stair Parts wood products come in a variety of species and profiles. The natural variations in grain and color will require tolerance for look and finish. Sanding to a finish will be required on most products unless stated otherwise before paint or varnish can be applied. Our blanks and notched posts are made of three layers of 1 (more for 3.5” posts) inch thick pieces pressed together.
