- In contrast to other lock systems, the locking elements in 4KS cylinders slide along the curve cuts on the key
- A total of 12 unsprung, solid locking pins are brought into a specific position via positive control of the 6 key curves and scanned via 2 control bars
- The key's overlapping curve cut makes it virtually tamper-proof
- The integrated drill protection in each cylinder provides additional protection
- From the inside, the cylinder is locked with a knob
- The cylinders feature a modular design
- Each system is unique and is manufactured to customer specifications
- A security card (proof of ownership) is provided with each system
The thumbturn cylinder is delivered without keys; these must be ordered separately.
Locking systems are special-order products. The customer does not have the right to return or exchange the product.
Delivery time is approx. 10-15 working days; if the order includes cylinders that are 61 mm or longer on the cylinder side, this is extended to 20 working days.
