The Balustrade System includes newel posts, balusters and rails which are combined as a post-to-post system or an over-the post system.
A Post-to-Post system is built with the rail cut to lengths which fit between the newel posts.
An Over-the-Post system is built with the rail placed on top of the newel posts as a continuous length.
