Multi-Point Pocket Combination Lock (Ultra-Thin Multi-Point Fork Type)
This multi-point pocket combination lock (ultra-thin multi-point fork type) is crafted from high-density zinc alloy. It is an ultra-thin, multi-point interlocking lock set designed specifically for screen doors. The fork-and-rod transmission mechanism drives multiple locking points to open and close simultaneously, enabling keyless operation. It features a single-wheel combination unlocking function, making operation convenient and effortless. All performance metrics meet industry standards, making it a high-end opening and closing hardware accessory for upgrading screen doors and windows in both residential and commercial projects.
Zinc Alloy Base Material, All Performance Tests Passed
All core components—including the main control panel, fork latches, and load-bearing brackets—are integrally die-cast from high-density zinc alloy. The overall structure offers sufficient rigidity and excellent resistance to deformation and wear, ensuring stable operation even during long-term, high-frequency opening and closing cycles.
The product is manufactured in strict compliance with the QB/T 3891‑1999 industry standard for door and window hardware. It has successfully passed a 200,000-cycle durability test for repeated opening and closing, with a locking force of up to 350 N, ensuring a secure and reliable lock; it has also passed a 500-hour neutral salt spray corrosion resistance test, making it resistant to oxidation and rust in humid environments such as balconies and outdoor areas, demonstrating outstanding corrosion resistance.
Single-dial combination unlocking design with multi-point fork interlocking
The lock body features a single combination dial with a fixed unlock code of “6,” allowing for keyless unlocking—simple and hassle-free. Turning the dial to the correct code activates the internal drive rod, which synchronously extends and retracts multiple sets of locking forks at the top and bottom. These multi-point locking mechanisms simultaneously engage to secure the screen door panel, ensuring even force distribution across the frame and providing superior protection and anti-theft performance compared to standard single-point locks. The ultra-thin faceplate design is particularly well-suited for narrow-frame profiles, resulting in a sleek and unobtrusive appearance after installation.
Compatible with Aluminum Profiles for Efficient and Convenient Installation and Commissioning
This product is specifically designed for aluminum alloy screen window profiles, suitable for profile thicknesses ranging from 12 to 30 mm. The embedded, ultra-thin, elongated panel can be concealed within the profile cavity, and most components can be pre-installed directly without the need for complex milling or drilling, ensuring quick and easy installation. Surface treatment processes can be customized according to customer requirements, and the color can be perfectly matched to the screen window profiles. The complete set of hardware accessories offers strong compatibility, making it suitable not only for individual home installation projects but also for bulk orders for real estate developments and complete sets for export.
