Widely suitable for residential, commercial, and various construction projects involving doors and windows, it provides outstanding security and protection.
High-Quality Materials, Precision Craftsmanship
The handle is made of high-strength zinc alloy through a single-piece die-casting process, resulting in a solid and stable structure that resists deformation and wear. It has successfully passed a 100,000-cycle opening and closing durability test, making it suitable for long-term use in high-frequency door and window operation scenarios. The product is manufactured in strict compliance with the QB/T5338-2018 industry standard for door and window hardware, ensuring all performance metrics are compliant and reliable. The surface finish supports customization and has passed a 500-hour neutral salt spray test, demonstrating excellent weather resistance and corrosion protection. It withstands the erosion of complex outdoor environments—including sunlight, rain, and temperature fluctuations—and remains resistant to rust, fading, and scratches even with long-term use. The latch has undergone rigorous tensile testing and can withstand a force of 350 Nm, ensuring a secure lock and strong resistance to prying and disengagement.
Secure Combination Design, User-Friendly Operation
Equipped with a three-digit dial combination lock, users can set their own unlocking code, eliminating the need to carry a key. A keyed version is also available as an option, balancing convenience with dual security. The 90° rotation design allows for effortless and smooth opening and closing of doors and windows. The concealed, flush-mounted design integrates seamlessly with the window sash, with no protruding parts, preventing bumps and scratches while complementing a variety of door and window decor styles.
Easy Installation, Wide Compatibility
Standardized pre-drilled mounting holes ensure simple and efficient on-site assembly, effectively reducing assembly time and labor costs for door and window manufacturers. Compatible with mainstream sliding doors and windows made of aluminum alloy, PVC-U, and other profiles, it can be used with various drive latches and door/window rollers, making it suitable for residential, commercial, and construction applications.
Stringent Quality Control and Stable Performance
Before leaving the factory, products undergo multiple professional tests, including a 100,000-cycle opening and closing endurance test, a 500-hour neutral salt spray test, and a 350 Nm latch pull force test. Manufactured in strict accordance with industry standards, they feature a robust and durable structure with a high safety factor, making them the preferred choice for security-grade door and window hardware among manufacturers, hardware wholesalers, and project purchasers.
