Product Description
Heavy-Duty Through-Handle
This heavy-duty two-way through-handle is designed for doors and windows, featuring a robust main body and through-square-shaft drive design. The handles on both sides operate in perfect synchronization, ensuring smooth opening and closing operations. The sturdy construction resists loosening, making it ideal for door and window accessories requiring dual-sided operation. It serves as a versatile opening and closing accessory for both residential and commercial projects.
Reinforced Body Structure
The handle body is precision-formed from reinforced zinc alloy or high-strength metal, resulting in a robust overall structure with excellent resistance to prying and wear. Even after long-term, repeated use, it remains resistant to loosening or wobbling. The surface features a white spray-painted or electrophoretic coating that is uniform and wear-resistant, complementing white door and window profiles for a clean, minimalist appearance.
The central connecting square shaft is made of high-strength galvanized steel, running through both sides of the handle. This ensures direct power transmission and even force distribution, enabling synchronized opening and closing of both handles. Operation provides clear feedback, and the lock engages with a distinct sense of security.
Quality Standards
Complies with QB/T 5338-2018 General Technical Standard for Door and Window Hardware and has passed continuous opening and closing tests, ensuring stable and reliable performance over the long term.
Through-Axis Interlocking Design
Featuring a left-right through-axis structure, operating one side drives the other to rotate synchronously, making it ideal for scenarios requiring opening and closing from both sides of the door or window. The handles are ergonomically curved for a comfortable, secure grip, and require moderate force to operate, allowing even the elderly and children to use them with ease.
The base and pivot shaft fit tightly together, ensuring smooth, even rotational resistance without jamming, play, or abnormal noises. After installation, the handles on both sides are symmetrically positioned, creating a clean appearance that enhances the overall aesthetic of the door or window.
Universal Installation Specifications
Featuring industry-standard mounting hole spacing and square-shaft drive specifications, this product is compatible with the lock cases and drive systems of most aluminum alloy, PVC-coated steel, and thermal break aluminum doors and windows.
Installation requires no complex hole modification; standard screws are sufficient for securing the unit, making it convenient for both new window installations and replacements of existing windows.
The product can be used independently or combined with hardware such as operating rods, locking points, and lock plates to form a multi-point locking system, enhancing the windows' and doors' sealing, burglary resistance, and wind resistance.
