The 4" ball space requirement rule gives you the maximum center-to-center distance between Balusters and still does not allow a 4" Ball to pass through at any point between the Balusters. When laying out Balustrade System, use the maximum center to center dimension or smaller to allow for a safe dimension to pass the 4" ball space requirement rule.

Each of our Newel Posts are constructed out of polyurethane and reinforced with high-density structural PVC. This provides the newel with more excessive strength to pass all BOCA National Building Codes and fully support over an eight-foot run of balustrade. With several sizes to choose from, the architectural newel posts not only provides an immense amount of strength, but also contributes to the fluid design of elegance for our polyurethane balustrade systems.
Along with our newel posts, we also offer a variety of Porch Posts that are reinforced with high-density structural PVC. These reinforced Porch Posts have a large load-bearing capacity. Our porch posts can also be field trimmed to various heights without losing load rating.

![]() 4" Sphere-Rule RequirementOne of the most well-known codes in the construction industry is the 4" Sphere Code, also known as the 4” ball rule. This Code states that spindles or balusters must be spaced close enough together so that a 4" ball cannot pass through any given space in between each spindle. Each of our spindles and balusters come with a recommended On Center Spacing. This measurement is designed to space the spindles as far apart as possible, while still passing the 4" ball code. |
