Cylinder 81.C15 according to VdS A
These cylinders offer basic protection against drilling and breaking open. They are particularly suitable for flat doors with material values to be protected up to € 130,000. Due to carbide inserts in the rotor, this version protects against drilling with carbide and HSS tools.
Cylinder 81.D15 according to VdS B
These cylinders offer increased protection against drilling and breaking open. They are particularly suitable for important lockable doors indoors and outdoors. Several carbide pins reliably protect the rotor against drilling out with carbide and HSS tools.
