Add distinctive elements to your vinyl railing project. Any of our 4"x 4" post caps and our 4" x 4" post skirt will fit this post. Post mounts are available to connect your newel post to concrete or to your deck. Made from premium quality vinyl, the Colonial Turned Newel Post Sleeve is easy to install and maintenance free. It can be shortened on site to match your specific application. If shortening, it is best to cut equal amounts from both the top and bottom.
