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

Multi-Point Fork-Type Automatic Pocket Lock
The main body of this multi-point fork-type automatic pocket lock is crafted from high-density zinc alloy, making it a complete multi-point interlocking lock system specifically designed for Screen Windows. It utilizes a fork-linkage transmission mechanism to achieve simultaneous opening and closing of multiple locking points. Supporting keyless operation and featuring a single-code wheel unlocking function, it offers effortless and convenient operation. With all performance metrics meeting industry standards, it serves as a high-end opening and closing hardware accessory for upgrading Screen 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, 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 durability test involving 200,000 opening and closing cycles, with a locking force of up to 350 N, ensuring safe and reliable locking. After undergoing a 500-hour neutral salt spray anti-corrosion test, it resists oxidation and rust in humid environments such as balconies and outdoor areas, demonstrating excellent corrosion resistance.

Single-Wheel Combination Lock with Multi-Point Interlocking Bolts
The lock body is equipped with a single combination wheel; turning it to the number 6 unlocks the door, eliminating the need to carry a key and making operation simple and hassle-free. Once the combination dial is set to the correct code, it activates the internal transmission linkage, driving multiple sets of upper and lower locking forks to extend and retract simultaneously. This multi-point locking mechanism securely engages the screen panel, distributing force evenly across the frame and providing superior security and anti-theft performance compared to standard single-point locks.

Compatible with aluminum profiles; quick and efficient installation and commissioning
Specifically designed for aluminum alloy Screen Window profiles, compatible with profiles 9 mm thick and above. The recessed long panel can be concealed within the profile cavity, and most components can be pre-installed directly, eliminating the need for complex milling or drilling, making installation simple and quick. Surface finishes can be customized to meet customer requirements, and colors can be perfectly matched to the Screen Window profiles. The complete set of hardware accessories is comprehensive and highly compatible, 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.
