Recessed Key-Operated Lock
This recessed key-operated lock features a concealed, elongated recessed design combined with a key-locking mechanism. It installs flush with the surface for a seamless, unobtrusive appearance and offers simple, convenient operation. Primarily designed for use with various types of aluminum alloy doors and windows, it balances practicality, aesthetics, and security against theft, making it widely used in residential, commercial, and various construction projects involving sliding doors and windows.
High-Quality Materials and Precision Craftsmanship
The lock body is made of high-strength zinc alloy through a single-piece die-casting process, resulting in a solid and stable structure with excellent resistance to deformation and wear. It can withstand frequent opening and closing of doors and windows over the long term, ensuring a durable and reliable service life. Surface finishes can be customized to meet specific customer needs. Having passed a 500-hour neutral salt spray test and a 4H surface hardness test, the lock exhibits outstanding weather resistance, corrosion resistance, scratch resistance, and wear resistance. Even when exposed to the elements outdoors for extended periods, it is unlikely to rust, fade, or become scratched. The recessed design allows the hardware to lie completely flush with the window sash surface, effectively preventing everyday bumps and scrapes. Its sleek, streamlined profile complements aluminum alloy doors and windows in a variety of interior design styles.
Key-Lock Design: Reliable Security
The built-in key lock cylinder structure effectively prevents doors and windows from being pried open by external force once locked, safeguarding indoor property while also preventing safety accidents such as children falling from windows they have opened on their own. Paired with a red status indicator, the locked and unlocked states can be clearly distinguished. The lock bolt engages firmly without loosening, effectively preventing doors and windows from accidentally sliding open and significantly enhancing safety during use.
Easy Installation and Strong Compatibility
The lock body features standardized mounting holes, making on-site assembly quick and effortless. This effectively reduces assembly time for door and window manufacturers and lowers labor costs. Designed specifically for aluminum alloy doors and windows, the product offers excellent versatility. It can be combined with hardware accessories such as sliding hinges and transmission latches to form a complete door and window hardware kit, and is compatible with various types of sliding and folding doors and windows.
Stringent Quality Control and Long-Term Warranty
Every recessed key-bar lock undergoes multiple professional performance tests—including corrosion resistance, wear resistance, and locking stability—before leaving the factory. With stable and reliable performance across all metrics, the product comes with an official 5-year warranty. Offering outstanding durability, peace of mind, and value for money, it is the preferred choice for aluminum door & window manufacturers, hardware wholesalers, and project purchasers.
