On a deck railing, balusters are the smaller, vertical pieces that run from your top rail down to your bottom rail in between the thicker posts. Deck balusters are sometimes called spindles or pickets. Balusters come in all shapes and sizes: round, square, flat, and even specially-shaped decorative balusters with unique designs. Deck balusters can be made of a wide range of materials including metal, wood, and glass.
