The 22mm Square Groove 4 Bar Top Hung Stay is a critical component for modern architectural ventilation. Unlike side-hung variants, this Window Hardware is calibrated to support the weight of the window sash from the top, ensuring that even under high wind pressure, the sash remains securely positioned at the desired opening angle.

Integrated into the Aluminum Alloy Hardware ecosystem, this stay utilizes a heavy-duty friction slider system. Manufactured from SUS304 Stainless Steel, it offers unparalleled resistance to atmospheric corrosion and structural fatigue, making it the benchmark for high-rise residential projects and premium office facades.

Structural Calibration

◈ Dynamic Friction Regulation

The Premium Hardware Solutions series by Luoqi utilizes a proprietary friction washer system. This allows the Top Hung window to remain stable at any intermediate angle, preventing "slamming" caused by weight or external wind drafts.

◈ High-Performance Glide Slider

Our heavy-duty nylon slider provides a self-lubricating interface between the track and the 4-bar linkage. This significantly reduces wear and tear in Luoqi Door Systems, ensuring a lifetime of silent and effortless operation.
