Casement and awning window snubbers are specialized hardware items used to reinforce the structural integrity of operable windows, particularly those that are tall, wide, or prone to bowing. These devices are typically installed at the center of the hinge side and work by minimizing sash deflection, maintaining the correct weatherstrip compression, and supporting the window under negative loading conditions,such as wind gusts or forced entry attempts. Snubbers play a critical role in reducing air and water infiltration, preserving energy efficiency, and extending the performance of your windows.

What Are Window Snubbers?

Window snubbers are small but essential parts mounted to both the window frame and sash. When the window closes, the snubber components engage, holding the sash tightly in place and compressing the weatherstripping for a secure seal. There are two main types: compression snubbers, which focus on seal integrity, and interlocking snubbers, which limit outward bowing under high negative pressure. Properly installed snubbers are especially important for large or heavy casement and awning windows, as well as some double-hung units, helping prevent the center of the sash from flexing outward over time.

Use Cases and Compatibility

Snubbers are recommended for:

  • Tall casement windows prone to bowing in the middle
  • Wide awning windows that require extra structural support
  • Applications where maximizing energy efficiency and air sealing is important
  • Situations where maintaining window warranty and manufacturer specifications are a priority

Most replacement snubbers in this collection are designed for compatibility with AmesburyTruth windows and hardware systems, but they are widely used as direct replacements in many North American window brands that specify or use AmesburyTruth components. Always verify the part number and compare your existing hardware's dimensions and finish to ensure the best fit.

Installation and Replacement Tips

For optimal performance, it's important to install snubbers at the manufacturer-recommended location,typically centered on the hinge side of the sash or frame. Two snubbers are commonly required per window. Ensure that mounting surfaces are clean and that fasteners are secure. When replacing, match the finish (such as E-Gard® coating for rust resistance) and material (usually steel or die-cast zinc) for consistent durability. Some popular options include a corrosion-resistant casement snubber with E-Gard finish and a concealed frame and sash mount model for anti-bow support.

Frequently Asked Questions

  • How do I know if I need to replace my window snubber? Visible bowing of the sash, difficulty closing the window tightly, or increased drafts can indicate a worn or missing snubber.
  • Are these snubbers suitable for non-AmesburyTruth windows? Many snubbers match dimensions and finishes found in other brands, but always compare your original part for best results.
  • What finish should I choose? E-Gard coating is recommended for corrosion resistance, especially in humid or coastal environments.
