Concealed Screen Code-Operated Automatic Lock
This concealed screen code-operated automatic lock is specifically designed for Screen Windows with hidden mesh. The lock body features a zinc alloy main structure paired with stainless steel internal components, and relies on a built-in spring mechanism to automatically lock when closed. Designed for indoor security to prevent children from accidentally opening the Screen Window, it is a high-quality hardware accessory that enhances the safety of your Screen Window.
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. The product is manufactured in strict compliance with the door and window hardware industry standard QB/T 5338‑2018. It has passed a durability test involving 200,000 opening and closing cycles, with a locking force of up to 350 N, ensuring a secure lock; it has also passed a 500-hour neutral salt spray anti-corrosion test, maintaining stable performance in the humid environment of a balcony and resisting oxidation and rust.
Two-way latch locking mechanism; indoor unlocking with the code “6”
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. Surface finishes can be customized in a variety of colors to meet customer requirements.
