Performance & Function

Provides stable load-bearing, controlled friction opening and smooth movement for medium to large casement windows. Suitable for both residential and commercial high-frequency use. As a friction stay hinge solution, it ensures structural safety and premium operational feel.

• Controlled friction for safe, stable opening
• Optimized for large or heavy window sashes
• Compatible with casement and top-hung systems

Material & Construction

Forged stainless steel components with CNC machining for higher mechanical strength, corrosion resistance and dimensional accuracy. This stainless steel friction stay ensures long-term durability in outdoor architectural environments.

• 202 stainless steel (economical corrosion resistance)
• 304 stainless steel (enhanced outdoor performance)
• Silent bearing structure for smooth motion
• One-piece forged links for superior fatigue resistance

Compatibility & Fitment

Designed to integrate with global-standard Euro groove systems and major aluminium profile specifications. Ideal for casement window hinge upgrades and large sash applications.

• Euro Groove 23 mm alignment
• Stack height fit: 12–14 mm
• Multi-length options for different sash sizes
• Suitable for 13.5 / 18 / 22 mm groove widths

Installation & Maintenance

Easy installation with standard pre-drilling positions. Suitable for both indoor and outdoor casement configurations. As a casement window hinge solution, it supports reliable long-term performance.

• 2–3 hinge sets recommended depending on sash load
• Maintain lubrication for long-term smooth operation
• Avoid corrosive chemical exposure
