EVVA 4KS rim cylinder AZ

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 facilities 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

Measurements:

case length: 25,3 mm
rosette: Ø 50 mm
mounting diameter: 28 mm
cylinder: Ø 34 mm

Technical characteristics:

springless technology
locking authorisation query in at least 18 query positions (authorisation positions)
12 springless, massive locking pins are brought into a specific position via positive control of the six key curves and scanned by 2 control bars
locking bar in the core controls the additional coding of the key
carbide drilling protection in core and body
steel balls as drilling protection for the cylinder fixing screws
picking and scanning protection
impact key protection
pulling and tear-off protection
locking path: 360°
locking bar for door thickness up to 50 mm
locking bar can be shortened every 5 mm by buckling

Execution:

reversible key system
vertical, easy key insertion
cylinder body and cylinder core: base material brass
slide coating of all locking elements
combination with electronic locking system possible

Key:

key thickness: 2,2 mm
reversible key made of special resistant nickel silver alloy
more stable and ergonomic due to the new bow shape
more compact due to shortened key tip
highest wear resistance
overlapping curve milling protects against key manipulation and ensures maximum safety
easy key insertion through uniquely rounded key tip
optional: key caps, key with coloured dot, key with extended key neck
the original 4KS key is produced exclusively by EVVA and is only available from an EVVA partner.
The fourth hidden curve: One of the three curves on one side runs asymmetrically on the other side. It is the hidden fourth curve that gives the 4KS its name.

Technical details

Unlike other locking systems, the locking elements in the 4KS cylinder move along the curves on the key. They are no longer pressed against a spring force. A total of 12 springless, massive locking pins are brought into a specific position via positive control of the six key curves and scanned by two control bars. A locking bar in the core controls the additional coding of the key. In total, the 4KS key is interrogated four times. This is 3 queries more than with other systems and offers maximum security.

The fourth hidden curve
One of the three curves on one side runs asymmetrically on the other side. It is the hidden fourth curve that gives the 4KS its name.

EVVA 4KS key features

Locking cylinder security
The innovative technologies of the 4KS cylinder offer sustainable protection against illegal opening methods:

Picking and scanning protection
The 4KS cylinder is equipped with several locking pins. It is not possible to tell which locking pin is effective in each individual case. Due to the freely movable position of the locking elements in the core, it is almost impossible to scan a milling pattern for a duplicate key. In addition, the springless function protects against impact picking.
Drilling protection
The carbide metal side control bar, the core drilling protection and the body drilling protection in the 4KS cylinder offer effective protection against drilling.
Impact key protection
With this complicated opening method, burglar professionals use a so-called impact key to try to bring the query positions in the cylinder into the correct position.

Options

Cylinder finishes:

standard finish: nickel
