A baluster is a vertical piece between a railing and other wood or the floor that adds support and safety; a short and decorative post or pillar that supports a top rail.Balusters-Learn What Features Are Important and Which Materials Are Best. Balusters serve two purposes: they enhance the design and beauty of railings and exteriors and they keep people and children safe from falling off decks and high outdoor areas. All balusters have structural and building code requirements.U.S. building codes mandate that balusters have no more than a 4-inch gap between them. This relatively tight amount of spacing still allows for visibility between spindles, but also stands as a safety measure to prevent small children from becoming stuck between spindles or from slipping through the balusters.
