A stair rail, also known as a handrail or banister, is a supportive railing that runs along the length of a staircase. It is an essential safety feature, usually installed on one or both sides of a staircase, providing stability and assistance to individuals ascending or descending the stairs. A stair rail is typically mounted at a standard handrail height, which ranges from 34 to 38 inches (86 to 97 centimeters) above the tread of the steps.
The primary function of a stair rail is to provide a secure grip and support for users, enabling them to maintain balance and minimize the risk of falls on the stairs. It acts as a physical barrier, ensuring that individuals have something to hold onto while navigating staircases, especially those with steep or narrow steps. Stair rails are commonly made of durable materials such as wood, metal, or plastic, depending on the desired aesthetics and durability.
Apart from its practical use, a stair rail also serves an aesthetic purpose by enhancing the overall appearance of a staircase. It can be designed in various styles, shapes, and finishes to complement the overall architectural style of a building or to meet individual preferences.
Stair rails are subject to safety regulations and building codes, which often prescribe requirements for their height, spacing, and strength. These standards aim to ensure that stair rails are capable of withstanding reasonable force and weight, providing a secure and reliable support system for users of all ages and abilities.
The etymology of the word "stair rail" can be traced back to the Middle English word "staire" meaning "flight of stairs" and "rayl" meaning "railing" or "barrier". The word "stair" comes from the Old English word "stiġer" which meant "a rising step" or "staircase". "Rail" has its roots in the Middle English word "reil" which was derived from the Old French word "raille" meaning "railing" or "barrier". Therefore, the combination of these two words, "stair rail", refers to the railing or barrier running alongside a flight of stairs.
