Frequently Asked Questions
What is the difference between attached and between-post balusters?
Attached balusters are face-fixed to the top and bottom rails. Between-post balusters sit inside a channel or groove. Attached balusters are easier to replace individually but may require more precise spacing to meet the 125mm gap rule.
Do attached balusters need to meet the same spacing rules?
Yes. The 125mm maximum gap rule applies regardless of attachment method. Whether balusters are attached, slotted, or welded, the clear gap must not allow a 125mm sphere to pass through.
