It features a sphere and beveled base. The post top installs with the flat cap and newel post. The newel finishes spans of balustrade with classic detail. The ball post top is easy to work with and moisture resistant. The unique closed cell structure of urethane prevents the moisture absorption that can cause peeling, cracking, staining and decay in other traditional materials, like wood or stone. Rigid, high-density urethane is also affordable and easy to work with.
