The surface mount tower system is designed for 4” x 4” vinyl posts in railing applications where the posts need to be mounted to a hard surface such as concrete, or this tower system can be used on wood decks when the substructure is modified as detailed at the end of this section. When installed as detailed below, vinyl posts using the post tower can meet post requirements for 36” and 42” high rail systems in one and two family residential applications. Vinyl railing can also be used in all other 42” high railing applications.
