Intermediate rails or balusters serve primarily as safety barriers in construction, particularly in stairways, balconies, and other elevated areas. Their primary function is to prevent falls and ensure that people, especially children and pets, cannot easily slip through spaces in the railing system. By creating a barrier that is typically built to specific height and spacing codes, these components enhance safety while offering stability in areas where individuals may be moving between different levels.

While balusters can also have decorative elements, their fundamental role is centered on enhancing safety. They are often designed with solid structural integrity to withstand impacts and provide reliable protection against accidental falls. This safety function is essential in both residential and commercial buildings, as it adheres to building codes and safety standards aimed at reducing the risk of injury.
