Product Description
European-Style Manual Window Opener
The handle base of this European-style manual window opener is made of thickened die-cast zinc alloy, while the connecting rod is crafted from stainless steel. Designed specifically for European-style top-hung windows and skylights, this manual opening and closing hardware uses a hand crank to drive the connecting rod, which pushes the window sash open and closed—making operation simple and effortless.
Premium Construction Materials
Zinc Alloy Handle + Stainless Steel Linkage
Rust-resistant, weather-resistant, and long-lasting construction
The entire manual operation base is made from a single piece of high-density zinc alloy die-casting, providing a sturdy, impact-resistant structure that resists cracking, loosening, or deformation even with frequent manual adjustments. The surface features a matte black spray coating that is durable, scratch-resistant, and resistant to fading or peeling.
The long support rod is machined from thickened stainless steel sheet, offering high toughness and resistance to bending; it resists rust and corrosion even in outdoor environments exposed to sunlight, humidity, and moisture. The internal transmission mechanism meshes smoothly, ensuring no jamming during the entire rotation of the crank, resulting in effortless, smooth opening and closing.
Precision Operation & Installation
The crank-linkage mechanism allows the window to be locked at any desired opening angle. Rotating the side crank handle extends the stainless steel linkage to push the window sash open. The opening angle can be locked at any position, allowing you to adjust ventilation as needed.
Even in high winds, the mechanism securely supports the window sash, preventing it from shaking or bumping into objects. The linkage length is compatible with most European-style casement windows and top-hung skylights.
Easy Installation Features
The base features pre-drilled standard mounting holes compatible with common European door and window profile sizes. Installation requires no grooving or cutting of profiles, making bulk assembly at door and window factories convenient and effectively reducing labor hours.
