Product Features & Advantages

• BS EN12209 Security: This mortise lock is tested and certified to BS EN 12209, delivering a security level suitable for commercial and medium-to-high risk environments. The internal mechanism is reinforced to resist picking, drilling, and forced manipulation, while the 2-turn deadbolt provides deeper engagement into the strike plate compared to standard residential locks. This extended throw significantly improves resistance against kick-in attacks and forced prying, making the lock well-suited for office entrances, retail storefronts, and shared-access buildings where both security and operational reliability are required.
• SUS304 Stainless Steel Durability: All major structural components are manufactured from SUS304 stainless steel, ensuring excellent resistance to corrosion caused by humidity, frequent cleaning, and environmental exposure. The lock has successfully passed 240-hour salt spray testing, demonstrating stable performance without surface rust, binding, or internal degradation. This material choice directly reduces the risk of lock jamming and extends service life, particularly in public buildings where door hardware is cleaned daily using chemical agents.
• Universal Backset Options: To accommodate diverse door designs and regional standards, the lock is available with multiple backset options ranging from 55 mm to 80 mm. This flexibility allows contractors to install the same lock model across different door thicknesses and profiles without structural modification. By eliminating the need for custom machining or adapter plates, installation time is reduced and on-site errors are minimized, improving efficiency in multi-door projects.
• 260-Minute Fire Resistance: Tested to EN 1634 standards, the lock maintains structural integrity and operational function for up to 260 minutes. During a fire event, the deadbolt and latch remain engaged to ensure the door stays closed, preventing the spread of smoke and flames while still allowing controlled egress when paired with appropriate exit hardware. This performance supports compliance with commercial fire safety regulations and is suitable for use on fire-rated doors in public and commercial buildings.

Application Scenarios

• School Administrative Entrances: Administrative areas in schools require controlled access while maintaining compliance with fire safety regulations. The lock’s fire-tested construction and compatibility with panic exit hardware support safe evacuation routes, while its robust mechanical design resists tampering and unauthorized entry. This use case clearly demonstrates suitability for educational facilities where safety, durability, and regulatory compliance are equally important.
• Hotel Lobby and Shared Access Doors: Hotel lobbies and shared access doors must combine fire safety compliance with durable operation under constant use. The 260-minute fire resistance supports fire-rated door assemblies, while compatibility with lever handles and door closers ensures smooth, quiet operation suitable for hospitality environments. For project specifiers, this application highlights how the lock fits into regulated public spaces without disrupting design consistency.
• Retail Storefronts: Retail storefront doors face elevated security risks due to visible merchandise and extended opening hours. The reinforced deadbolt design and anti-drill performance directly address common break-in methods used after business hours. At the same time, corrosion-resistant SUS304 construction prevents performance issues caused by frequent cleaning and exposure to street-level humidity, making this lock a practical choice for shopping centers and standalone retail units.

Production Process & Quality Control

1. Material Testing: XRF testing confirms SUS304 chemical composition with approximately 18% chromium and 8% nickel, ensuring genuine corrosion resistance.
2. Precision Machining: Critical components are CNC-machined with tolerances controlled within ±0.005", ensuring consistent compliance with BS EN 12209 performance requirements.
3. Assembly & Calibration: Internal mechanisms are lubricated with aerospace-grade lubricants, and deadbolt movement is calibrated to ensure smooth, reliable two-turn operation throughout the product’s service life.
4. Performance Testing: Each unit undergoes functional testing before shipment, with random samples subjected to fire resistance, anti-intrusion, and salt spray tests.
5. Final Inspection: A 100% final inspection checks surface finish, deadbolt alignment, and certification markings prior to secure packaging and delivery.
