The JNF Series 400 narrow cylinder lock is specifically developed for narrow profile doors made of aluminium, steel, and other metal profiles and is available with a backset of 25, 30, and 35 mm. Thanks to its compact construction and high-quality materials, this lock provides a durable and reliable solution for both residential and professional applications.

This narrow cylinder lock is suitable for a European profile cylinder and is manufactured from high-quality stainless steel EN 1.4301 (AISI 304) . As a result, it offers excellent resistance to wear and corrosion, even with intensive daily use. The brushed finish provides a sleek and timeless look that perfectly complements modern architectural door hardware.

For extra comfort, the lock features a silent, reversible latch with an integrated nylon silencer. This ensures the door closes smoothly and silently. The latch can be easily reversed, making the lock suitable for both left- and right-opening doors.

In addition, the narrow lock is equipped with an internal spring mechanism that helps reduce play between the door handle and the spindle. This ensures stable operation and contributes to a longer lifespan of the hardware.

The JNF Cylinder Lock Series 400 complies with the EN12209 Grade 3 standard and combines durability, reliability, and ease of use in one high-quality solution for narrow profile doors.
