Intersteel security rosettes are available with and without core pull. Core pull protects the cylinder against drilling and stretching of the cylinder core.
These security rosettes with core pull are provided with an SKG*** quality mark.
Core pull protection has been commonplace in new buildings in NL since the end of 2013 and since April 2014 for existing buildings.
These security rosettes have a diameter of 54 mm.
The outside has a thickness of 12 mm and the inside a thickness of 8 mm.
Both safety plates are connected from the inside with the supplied patent bolts.
These SKG3 security rosettes are suitable for a door thickness of 36 - 54 mm.
The Profile Cylinder overhang is: Min. 7.5mm - Max. 11.5mm.
This means that the cylinder may protrude at least 7.5 mm and max 11.5 mm on the outside, in connection with the core pull protection.
Longer patent screws are optionally available for larger door thicknesses.
These security rosettes are made of stainless steel with a matt black finish (RAL9005) and contribute to a safer home.
