High-Quality Materials and Rigorous Testing Ensure Stable Performance
The handle panel is made of high-density zinc alloy through one-piece die-casting, making it sturdy and durable. Core internal components, such as the spring and latch, are crafted from stainless steel, offering excellent wear resistance and resistance to deformation, ensuring they remain secure even after long-term, repeated use.

When closing the screen panel, the latch automatically extends via a built-in spring to lock the screen—locking instantly upon closure with smooth, jam-free operation. The lock body features a single combination dial with a fixed unlock code of “6”; simply turn the dial to unlock. Paired with a stainless steel latch plate, the two-way hooks engage securely.
