EVVA 4KS camlock cylinder MB23G

EVVA 4KS camlock cylinder / lever cylinder MB23G

EVVA 4KS (4 Curve System) is the most resistant system among mechanical locking systems. With its patented springless curve technology, 4KS is suitable for the toughest applications such as high up in the mountains or in production plants with high levels of dirt. The reversible key offers a comfortable insertion behaviour and turns easily and quietly in the cylinder. Of course, 4KS also has an EVVA-own feature: the overlapping curve milling. This guarantees maximum security and prevents key manipulation within the locking system.

The patented reversible key system is suitable for highly complex structured locking systems.

Patent protection until 2035
