Fork Type Multi Point Zinc Alloy Pocket Lock Interlocking for Screen Window

Multi-Point Fork-Type Pocket Lock
This multi-point fork-type pocket lock is crafted from a composite material combining zinc alloy and stainless steel. Designed specifically for Screen Windows, it is part of a complete multi-point interlocking lock system. Utilizing a fork-linkage transmission mechanism, it enables simultaneous opening and closing of multiple locking points. It features keyless operation and a built-in combination unlocking function, making operation effortless and convenient. All performance metrics comply with industry standards, making it a high-end opening and closing hardware accessory ideal for upgrading Screen Windows in both residential and commercial projects.

Zinc-Aluminum Composite Base Material, Meets All Performance Standards
Core components—including the main control panel, fork latch, and load-bearing bracket—are integrally die-cast from high-density zinc alloy, while the transmission linkage and latch components are paired with high-strength stainless steel parts. The overall structure offers sufficient rigidity, excellent resistance to deformation and wear, and remains stable even during long-term, high-frequency opening and closing operations.
The product is manufactured in strict compliance with the QB/T 5338‑2018 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 safe and reliable locking. After undergoing a 500-hour neutral salt spray corrosion resistance test, it demonstrates outstanding corrosion resistance and is resistant to oxidation and rust in humid environments such as balconies and outdoor areas.

Combination Lock Mechanism with Multi-Point Interlocking
The lock body is equipped with a single combination dial, with the fixed unlock code set to the number 6, enabling keyless unlocking for simple and hassle-free operation. Turning the combination dial activates the internal transmission linkage, which simultaneously drives multiple sets of upper and lower locking bolts to extend and retract. The multi-point locking mechanism engages to securely lock the screen panel, distributing force evenly across the frame and providing superior security and anti-theft performance compared to ordinary single-point locks.

Compatible with Aluminum Profiles for Efficient and Convenient Installation and Commissioning
Designed specifically for aluminum alloy Screen Window profiles, it is compatible with profile thicknesses ranging from 18 to 35 mm. The recessed long faceplate can be concealed within the profile cavity, and most components can be pre-installed directly, eliminating the need for complex milling or drilling. Installation is quick and straightforward. Surface treatment processes can be customized to meet customer requirements, and colors can be perfectly matched to the Screen Window profiles. The complete set of hardware components offers strong compatibility, making it suitable not only for individual installation in residential Screen Windows but also for large-volume orders in real estate projects and the export of complete hardware sets.
