Top rails are supplied in standard sections of up to approximately 2.4 metres. Longer runs are divided into equal lengths and joined so that the joints are evenly spaced. The available lengths depend on the material and balustrade system. Extra-long sections are available in some materials for a design with fewer joints.
Examples include aluminium up to approximately 4.4 metres and oak or jatoba around 3 metres at aluminium balustrades, and up to 4.4–5 metres at stainless steel or aluminium for post-free railings. The exact maximum lengths are shown in the configurator for the materials available in the selected system.
