Hello, And thank you for your question !


The building code reuirememnts for ballistars (pickets) on both stairs and deck/balconies is 4 inches in the opening. No object larger than 4 inches in diameter mey be able to pass through the opening of a ballistar. This was instituted because of kids and animals getting stuck between them (their heads)
