What is Casement Window Friction Stay?

Casement Window Friction Stay is a core hardware component connecting the window sash and frame, allowing smooth opening, closing, and secure positioning at any desired angle. It supports the sash weight, ensures operational safety, and enhances the durability and wind resistance of casement windows.

To meet different window styles and environments, Kingbo offers a full range of specialized solutions:

Heavy Duty SUS304 Friction Stay for Parallel Opening Window: Designed for large curtain walls and parallel opening windows. Made from solid SUS304 stainless steel, it supports heavy sashes up to 300kg, allows precise gap adjustment, and improves sealing performance. It addresses common issues like insufficient load capacity, difficult adjustment, and deformation of standard stays, making it ideal for commercial buildings and high-end residential projects.

Key Functions

· Load Support: Carries sash weight steadily and prevents sagging

· Angle Positioning: Holds securely at any opening angle

· Wind Resistance: Enhances stability in high-rise and coastal areas

· Smooth Operation: Slides smoothly without jamming or noise

· Safety Control: Limits opening width for child protection

How to Choose the Right Casement Window Friction Stay

Selecting the right friction stay depends on sash weight, dimensions, installation environment, and functional requirements. Follow these guidelines:

1. Select by Sash Weight 

· Standard casement windows usually need stays supporting up to 33kg.

· Large or heavy sashes, and curtain wall systems, require heavy-duty stays to avoid overloading.

2. Select by Sash Size 

· Common lengths range from 300mm to 800mm.

· Correct length of Casement Window Friction Stay ensures smooth operation, avoids frame collisions, and provides adequate support.

3. Select by Environment and Functions 

· Coastal or humid areas benefit from SUS304 stainless steel for corrosion resistance.

· High-rise or typhoon-prone regions require multi-point locking for wind pressure resistance.

· Safety-focused locations (homes, schools, hospitals) benefit from Window Limiter Stainless Steel Friction Stay Adjustable, which reliably locks the opening angle, prevents accidental closing, and restricts opening width.

4. Select by Quality Standards 

· Premium stays feature oxide film thickness ≥15μm for better weather resistance.

· They pass over 50,000 opening/closing test cycles for stable, long-term performance.
