This stainless steel set of security roses with extra protection against burglary is made of matt brushed stainless steel and is provided with SKG*** quality mark. By using solid stainless steel this cylinder set has a long life. Because the inner rosette can be concealed, the inside is immediately finished off nicely. The security fitting is provided with security pinhole protection, which protects the cylinder against pulling out and drilling the cylinder core. Since the end of 2013 key pull protection has been compulsory in new buildings and since April 2014 also in existing buildings. The security hardware is also SKG*** approved, which means that it is extra heavy burglary resistant hardware. This set of security rosettes also complies with the Police Quality Mark Safe Living (PKVW).
