Newel post mounting plates are one of the truly beautiful inventions in the world of staircase installation and remodeling. Attach a post to a finished surface with absolute ease – the inner circles attach directly to the post, and the outer holes attach directly to the floor. Finish out the trim around the exposed edges and move forward. Time-saving at it’s absolute finest. This kit includes multiple plates for installing on an angle, such as a stair or decorative knee wall.
