Manufactured using solid 304 stainless steel along with brass or zinc alloy internal parts, the lock ensures long-term durability under high-frequency use. It meets CE EN12209 and DIN 18251 standards with a tested lifespan of 200000 cycles, while also achieving EN1634 fire resistance up to 240 minutes, offering both mechanical reliability and fire safety compliance for demanding environments. The reversible latchbolt allows flexible installation without additional modification, improving efficiency during bulk installation projects. Compatibility with Euro profile cylinders ensures easy integration into existing door systems.

Narrow frame doors require precise locking systems that balance strength, compliance, and installation flexibility. The Narrow Stile Mortise Lock DDML023 is engineered for slim-profile door applications where space is limited but performance standards remain uncompromised. With a compact case structure and multiple backset options ranging from 20 mm to 35 mm, this lock integrates smoothly into aluminum profiles, steel doors, and wooden narrow stile systems commonly used in commercial and architectural projects. Tested to EN12209 Grade 3 with 200,000 operational cycles and certified to EN1634 with a 240-minute fire rating, it meets strict European compliance requirements for safety-critical installations. Its narrow design combined with robust internal mechanics makes it suitable for both interior and exterior swing doors where durability, fire safety, and standardized configuration are essential.
