12-inch four-bar window hinge

Product Introduction: 12-Inch Four-Bar Window Hinge

The 12-Inch Four-Bar Window Hinge is a compact yet durable solution for top-hung and side-hung outward-opening windows, commonly used in both residential and light commercial applications. Engineered for smooth operation, precise positioning, and enhanced ventilation, this hinge is ideal for mid-size window sashes requiring secure, guided movement.

Key Features:

Four-Bar Linkage Design: Offers stable, friction-controlled opening and closing while guiding the sash along a safe and consistent path.

Premium Materials: Manufactured from stainless steel (Grade 304 or 316) for excellent corrosion resistance, especially in coastal or humid environments.

Friction Stay Functionality: Built-in adjustable friction sliders allow the window to stay open at multiple angles without needing additional support mechanisms.

Space-Efficient: The 12-inch size is ideal for moderate-sized windows, providing a good balance between ventilation and structural integrity.

Smooth, Silent Motion: Nylon or brass friction slides reduce wear and enable quiet, smooth operation over thousands of cycles.

Stack Height Options: Available in 13mm or 17mm stack height to suit various frame profiles.

Easy to Install: Standard screw hole patterns make it compatible with aluminum, uPVC, or timber window frames.

Applications:

Top-hung or side-hung casement windows

Ventilation windows in kitchens, bathrooms, and offices

Medium-sized aluminum or uPVC window systems

Projects requiring controlled opening, weather resistance, and space efficiency
