Vertical Components of a Railing: What Are They Called?

Brief Summary

The vertical pieces in a railing system are most accurately referred to as balusters. However, they may also be called spindles or pickets, depending on the specific design and regional terminology.

Expanded Answer

Balusters: The Technical Term

• Definition: Balusters are the vertical members that support the handrail and fill the space between the newel posts, forming the balustrade. They are crucial for safety, preventing falls, and also contribute to the aesthetic appeal of the staircase or railing.
• Origin: The term “baluster” is derived from the Italian word “balaustra,” which means “wild pomegranate flower.” This is a nod to the shape of early balusters, often resembling the bulbous form of a pomegranate bud.
• Material & Style: Balusters can be crafted from various materials, including wood, metal, glass, and even stone or concrete. They come in a wide array of designs, from simple turned or square profiles to ornate and intricate carvings.

Spindles & Pickets: Alternative Terms

• Spindles: This term is often used interchangeably with “baluster,” particularly for simpler, thinner designs or in casual conversation. It may also refer to the rotating rod used in spinning yarn, which bears some resemblance to the elongated shape of some balusters.
• Pickets: This term is more commonly used for exterior railings, especially on decks or porches. Pickets are typically vertical boards with a pointed or rounded top.

Function & Importance

• Safety Barrier: The primary function of balusters is to prevent falls by creating a protective barrier along the edge of the staircase or elevated platform. Building codes mandate specific spacing requirements (usually a maximum of 4 inches) to ensure child safety.
• Structural Support: While the main structural support comes from the newel posts and handrail, balusters also contribute to the overall strength and stability of the railing system.
• Aesthetic Element: Balusters play a vital role in the visual appeal of a staircase or railing. Their style, material, and arrangement can significantly impact the overall design aesthetic.

Building Code Compliance

• Spacing: Balusters must adhere to the 4-inch sphere rule, meaning a 4-inch diameter sphere should not be able to pass through any opening in the balustrade.
• Height: The minimum height for balusters and the entire railing system is typically 34-38 inches for residential staircases and 42 inches for commercial applications.
• Strength: Balusters and their attachment methods must be strong enough to withstand anticipated loads and forces, ensuring safety and preventing collapse.

Conclusion

While the terms “baluster,” “spindle,” and “picket” are sometimes used interchangeably, understanding their technical distinctions is important for clear communication and accurate descriptions. Whether you call them balusters, spindles, or pickets, these vertical members play a crucial role in the safety, functionality, and aesthetic appeal of any staircase or railing system. By choosing the right style, material, and installation method, you can create a beautiful and safe structure that complements your home’s design.
