Square Combination Lock Handle
This square combination lock handle features a minimalist and elegant design with clean, square lines. Equipped with a three-digit combination dial, it allows you to lock doors and windows securely without carrying a key. Installation and operation are simple and convenient, and it is compatible with aluminum and PVC-U profile doors and windows. Combining an attractive appearance with reliable security performance, it is widely used in residential homes, commercial stores, and various construction projects.
High-Quality Materials and Precision Craftsmanship
The handle is made from high-strength zinc alloy through a single-piece die-casting process, resulting in a sturdy and stable structure with excellent resistance to deformation and wear. It can withstand frequent opening and closing over the long term, ensuring a durable and reliable service life. The surface features a fluorocarbon coating with outstanding weather resistance. Having passed a 500-hour neutral salt spray test and a 4H surface hardness test, it effectively withstands the erosion of complex outdoor environments—including sunlight, rain, and temperature fluctuations—and remains resistant to rust, fading, and paint scratches or peeling even with long-term use. Available in two classic colors—black and white—as standard, the product also supports customization of exclusive colors and surface finishes based on customer needs. Its bold, square lines complement a variety of modern home decor styles, combining both aesthetic appeal and practicality.
Three-Digit Combination Lock Design: Convenient and Burglar-Proof
The handle features a three-digit combination dial, allowing users to set their own unique unlocking code. This eliminates the hassle of carrying traditional keys and the trouble of being locked out if they’re lost. Once locked, it effectively prevents forced entry while also preventing children from opening doors and windows without permission, thereby avoiding potential safety hazards. The side-mounted push-to-lock button provides dual protection alongside the combination lock, ensuring smooth and effortless opening and closing. The wide, comfortable grip makes daily operation of doors and windows effortless and intuitive.
Easy Installation and Wide Compatibility
The product features a standardized installation structure, enabling time-saving and efficient on-site assembly that effectively reduces assembly time and labor costs for door and window manufacturers. It is compatible with the two major door and window profiles—aluminum alloy and PVC-U—and suits various types of sliding doors and windows. It can be used in conjunction with hardware accessories such as rollers and latches, making it a flexible solution for a wide range of applications, including residential, commercial, and construction projects.
Stringent Quality Control and Long-Term Warranty
Every square dial combination lock handle undergoes multiple professional performance tests—including corrosion resistance and wear resistance—before leaving the factory. All parameters meet standards and remain consistent. Backed by an official 5-year warranty, these handles offer durability, peace of mind, and outstanding value, making them the top choice for door and window manufacturers, hardware wholesalers, and project procurement teams.
