The Ribbon Twist Series have wider, more flowing twists; ribbon-like that offer a softer look compared to the typical standard twists. The balusters are 1/2″ or 9/16" tube with a doweled top for easy installation. The single and double butterfly designs sit elegantly and perfectly in a traditional styled home. Combine them with other balusters; either in this wrought iron collection or with a different series; such as to compliment from our Scroll Collection. No matter which selection and pattern you may choose, you can be guaranteed a winning combination with the Ribbon Series by StepUP Stair.
