What is the difference between square top and pin top baluster?
Square Top vs. Pin Top Balusters: Understanding the Difference
Brief Summary
Square top and pin top balusters differ primarily in their top design and installation methods. Square top balusters have a square top section that fits into a grooved handrail, while pin top balusters have a rounded top designed to be inserted into drilled holes in the handrail.
Expanded Answer
Square Top Balusters: The Traditional Choice
- Design: Square top balusters typically feature a turned or decorative central section with square-shaped top and bottom sections. These square sections are designed to fit snugly into a plowed (grooved) handrail, providing a strong and secure connection.
- Installation: Installing square top balusters requires a plowed handrail with a corresponding groove or slot. A fillet, a small piece of wood, is often used to fill the gap between the baluster and the handrail for a seamless look. The balusters are then glued and/or nailed into the handrail and the treads or shoe.
Pin Top Balusters: Simplicity & Versatility
- Design: Pin top balusters have a turned or decorative central section with a rounded, pin-like top. This pin is inserted into a hole drilled directly into the handrail, eliminating the need for plowing.
- Installation: Installing pin top balusters is generally considered easier and faster, as it doesn’t require a plowed handrail. The balusters are simply glued and/or nailed into the drilled holes in the handrail and the treads or shoe.
Choosing the Right Style
- Aesthetics: Square top balusters are often associated with more traditional and formal staircase designs, while pin top balusters offer a simpler and more versatile look that can complement various styles.
- Handrail Design: If you’re using a pre-plowed handrail, square top balusters are the obvious choice. If you prefer an unplowed handrail or are working with metal railings, pin top balusters are more suitable.
- Installation Complexity: Pin top balusters are generally easier to install, as they don’t require the additional step of plowing the handrail. However, precise drilling is essential for a secure fit.
Building Code Considerations
- Strength & Safety: Regardless of the style, both square top and pin top balusters must be securely attached to the handrail and treads to ensure stability and safety.
- Spacing: Building codes in the USA mandate a maximum spacing of 4 inches between balusters to prevent children from passing through.
- Height: Balusters must also meet minimum height requirements, typically 34-38 inches, for adequate fall protection.
Conclusion
The choice between square top and pin top balusters depends on your design preferences, handrail style, and installation considerations. Both offer unique aesthetic appeal and can create a beautiful and functional staircase. Consider the overall style of your home, the existing handrail, and your comfort level with installation techniques when making your selection.
