Our Round Series Hollow wrought iron balusters are 1/2" round and are easily installed into any of our wood handrails. They include several variations that can be used to create a wide variety of uniquely designed patterns. Also, use our StairBuilder to design your balustrade and see what it will look like before you buy. As with all of our wrought iron balusters, this series is available in several standard powder coat colors and we can custom powder coat as well.
