What are the sticks in a railing called?

Demystifying Railing Terminology: The Vertical “Sticks”

Brief Summary

The vertical “sticks” that support the handrail and create the infill within a railing system are most commonly known as balusters. However, depending on the context or specific design, they might also be called spindles or pickets.

Expanded Answer

Balusters: The Technically Correct Term

• Definition & Function: Balusters are the vertical posts or pillars that run between the handrail and the treads (steps) or a bottom rail. They serve as a crucial safety barrier, preventing falls, and also contribute to the overall aesthetic appeal of the staircase or railing.
• Etymology: The word “baluster” originates from the Italian word “balaustra,” meaning “wild pomegranate flower,” a nod to their often bulbous shape in historical architecture.
• Versatility & Variety: Balusters come in a wide range of styles, materials, and shapes, offering endless possibilities for customizing the look of your staircase.

Spindles: A Common Synonym

• Usage: “Spindle” is often used interchangeably with “baluster,” especially in casual conversation or when referring to simpler or thinner designs.
• Origin: The term “spindle” likely stems from its resemblance to the tool used for spinning fibers, which shares a similar elongated and slender shape.

Pickets: Used for Exterior Railings

• Definition & Function: Pickets are vertical boards used in fences and outdoor railings, typically with a pointed or rounded top. While technically different from balusters, they serve a similar function in providing a protective barrier.
• Usage in Staircases: In some cases, “picket” might be used informally to describe the vertical supports in an exterior staircase railing, especially if they resemble fence pickets in design.

Materials & Styles

• Wood: Wood balusters, often made from hardwoods like oak or maple, offer warmth and natural beauty. They can be turned, carved, or shaped into various profiles, complementing both traditional and contemporary designs.
• Metal: Metal balusters, typically made from wrought iron or steel, provide strength, durability, and a modern aesthetic. They can be fabricated into a wide range of designs, from simple geometric shapes to intricate scrolls and twists.
• Glass: Glass balusters create a sense of openness and allow light to pass through, making them ideal for contemporary or minimalist spaces. Tempered glass is commonly used for safety.

Building Codes & Safety

• Spacing: Regardless of the term used, building codes in the USA mandate a maximum spacing of 4 inches between vertical supports in a railing system. This is known as the “4-inch sphere rule” and is designed to prevent children from passing through or getting stuck.
• Height: The overall height of the railing system, including the balusters/spindles, must meet minimum requirements, typically 34-38 inches for residential staircases.

Conclusion

While several terms are used to describe the vertical supports in a railing, “baluster” remains the most technically accurate. However, “spindle” is a common and widely understood synonym. “Picket” is typically used for exterior railings, though it may sometimes refer to staircase supports, particularly in informal settings. Understanding these terms and their subtle distinctions can help you communicate effectively and make informed decisions about your staircase design. Remember that, regardless of the terminology, safety and building code compliance are paramount when choosing and installing these essential railing components.
