Custom-length profile cylinder – ready in just 15 minutes
Modern door security and functionality are about much more than mechanics. Today, flexibility, precision, and the ability to adapt quickly to the unique requirements of each project are just as important.
Modular construction offers an innovative way to create a profile cylinder tailored to virtually any door thickness—quickly, efficiently, and without compromising security, functionality, or aesthetics.
What Is a modular profile cylinder?
When choosing a traditional profile cylinder, limited size availability is often a challenge. The required length may not be immediately available, meaning it has to be specially ordered and delivered, or the cylinder purchased turns out to be the wrong size. This can create unnecessary stress -especially when a profile cylinder has failed or a door has been broken into. How do you secure the door if the replacement cylinder you need is not available in stock?
The solution is the S11 modular profile cylinder from Portuguese manufacturer JNF. Unlike conventional profile cylinders, the S11 features a modular design consisting of interchangeable components that can be combined to create a cylinder in the exact length required for your door.

Flexibility that saves time and resources
The modular design of the JNF S11 profile cylinder makes it possible to create both standard and non-standard cylinder sizes in symmetrical and asymmetrical configurations. Unusual door thicknesses no longer have to delay door installation or project completion. For door manufacturers and joinery workshops, there is no need to keep a large inventory of cylinders in different lengths. Instead, cylinders can be assembled to the exact dimensions required for each project, reducing stock levels and simplifying logistics
Whether it's a renovation project with unpredictable door dimensions or a high-end architectural project with custom-made doors, the JNF S11 adapts effortlessly to the task. Its modular design reduces lead times, simplifies inventory management, and delivers a perfectly tailored lock cylinder whenever and wherever it's needed.
Everyday security and reliability
The modular design of the profile cylinder does not compromise its security performance. The JNF S11 profile cylinder complies with the European standard EN 1303, ensuring a high level of security and reliable everyday operation. TIts construction features five spring-loaded pins on each side of the cylinder, while the number of possible key combinations exceeds 100,000.
