Multi-Point Combination Lock with Lift-and-Slide Handle
This multi-point combination lock with a lift-and-slide handle is specifically designed for small hinged Screen Windows and serves as a complete hardware set for opening and closing them. It features a recessed, hidden long faceplate paired with a lift-and-slide handle mechanism and includes a combination unlocking function, allowing you to easily open the Screen Window without carrying a key. It utilizes a transmission linkage to achieve synchronized multi-point locking in both vertical directions, ensuring a secure lock and simple operation. This makes it an integrated hardware solution for both residential and high-end commercial Screen Windows.
High-Quality Alloy Components for Stable and Durable Performance
The core components of the lock body are crafted from zinc alloy, providing ample structural rigidity and excellent wear and corrosion resistance. The product is manufactured in strict compliance with the QB/T 5338‑2018 standard. It can withstand a maximum locking force of 350 N and has successfully passed a durability test involving 200,000 opening and closing cycles, ensuring stable operation even with long-term, high-frequency use. Additionally, it has passed a 500-hour neutral salt spray anti-corrosion test, making it resistant to rust and jamming even during prolonged use in the humid environment of a balcony.
Retractable Hidden Handle with Multi-Point Interlocking
The handle features a retractable, hidden design that tucks away into a groove in the panel. To open, pull down the handle to activate the transmission switch, then unlock using the combination dial—eliminating the hassle of carrying keys. The entire lock set is equipped with upper and lower drive rods that drive the Screen Window’s upper and lower locking points to extend and retract synchronously, achieving multi-point locking. Compared to single-point locking, this ensures more even force distribution, significantly enhancing locking reliability and sealing performance. The lock panel features an embedded profile groove, resulting in a flat surface without protrusions and a sleek, refined appearance; it supports both left- and right-opening configurations.
Wide range of compatible profiles; customizable surface finishes
Specifically developed for aluminum alloy small casement Screen Window profiles, it is compatible with Screen Windows with wall thicknesses ranging from 18 to 35 mm. The surface treatment of the lock body can be customized according to customer requirements, making it suitable for high-end home improvement retail and large-scale construction projects. It can be supplied as a complete set with other small casement Screen Window hardware, such as top-and-bottom hinges.
