Iron balusters — also called wrought iron spindles — are the vertical metal bars that fill the space between your handrail and the stair treads or base rail. Swapping dated wood spindles for iron is one of the fastest, highest-impact ways to modernize a staircase. BuyRailParts ships iron balusters direct in hollow and solid styles — plain bars, twists, baskets, scrolls and knuckles — in finishes like satin black and oil-rubbed bronze.
Measure your existing baluster spacing, then pick a profile that fits your home: plain rectangular and square bars read modern, while twists, baskets and scrolls suit traditional stairs. Many residential guards are subject to a 4-inch sphere rule, but requirements and exceptions vary; confirm the current local code and your inspector's requirements. Add baluster shoes to finish the connections.
