BR-608B Single Cylinder Swing Door Lock, Ergonomic Rear Fingerprint Handle Aluminum Zinc Alloy Lock with Interior Thumbturn for Aluminum Swing Doors

BR-608B single cylinder swing door lock combines premium aluminum alloy housing, zinc alloy fittings and precision copper internal components, delivering robust structural strength, excellent corrosion resistance and stable daily operation for aluminum door systems. The lever handle is shaped following ergonomic and aesthetic design principles, with well-proportioned dimensions and a smooth contour that fits naturally in the hand, reducing hand fatigue during frequent daily use. Fingerprint recognition is discreetly integrated on the back of the handle for fast, keyless one-touch access, while a traditional key cylinder remains as a reliable backup unlocking method. This door lock adopts a practical single-sided cylinder configuration: the exterior side uses a key cylinder for outdoor locking and unlocking, while the interior side is fitted with a thumbturn knob for quick, tool-free indoor operation, balancing external security and internal convenience. It is precision manufactured to fit standard aluminum swing door profiles, making it ideal for residential entry doors, interior security doors and light commercial door applications. As a popular model targeted at the Mexican market, it balances clean modern styling, practical security features and consistent build quality. Bulk wholesale orders and OEM customization are supported to meet the needs of local distributors and engineering projects.
