Final answer:
The entire system of balusters, handrails, and related support pieces is referred to as a balustrade, an architectural feature that provides support and safety.
Step-by-step explanation:
A baluster is an upright support, often a vertical moulded shaft, square, or lathe-turned form found in stairways, parapets, and other architectural features. In furniture construction it is known as a spindle. Common materials used in its construction are wood, stone, and less frequently metal and ceramic. A group of balusters supporting a handrail, coping, or ornamental detail is known as a balustrade.
The entire system of balusters, handrails, and related support pieces in architectural terminology is often referred to as a balustrade. This architectural feature is commonly found on staircases, porches, and balconies, providing support and safety as well as contributing to the aesthetic appeal of a building. A balustrade consists of a series of balusters or spindles that support the handrail, which is the part you hold onto when ascending or descending the stairs or standing on a balcony.
